10). A student appeared in the Mock CAT. The test paper contained 3 sections namely QA, DI and VA. The percentage marks in all VA was equal to the average of percentage marks in all the 3 sections. Coincidentally, if we reverse the digit of the percentage marks of QA we get the percentage marks of DI. The percentage marks in VA scored by student could be:

A. 81

B. 48

C. 66

D. 69

Correct Answers: C

Solution / Explanation:

Let the percentage marks in QA =(10a + b)%
Let the percentage marks in DI = (10b + a)%
Let the percentage marks in VA = x%

Now, according to the question, we have,

(10a+b)+x+(10b+a) / 3 = x
11a+11b+x = 3x
or, x=11(a+b) / 2

Clearly, we can see that the percentage of the VA section will be a multiple of 11
So, required answer will be 66

11). Every month a man consumes 25 kg rice and 9 kg wheat. The price of rice is 20% of the price of wheat and thus he spends total ₦350 on the rice and wheat per month. If the price of wheat is increased by 20% then what is the percentage reduction of rice consumption for the same expenditure of ₦350? Given that the price of rice and consumption of wheat is constant:

A. 40%

B. 25%

C. 36%

D. 24%

Correct Answers: C

Solution / Explanation:

Let the price of wheat is x per kg. Then price of wheat will be 5x per kg.
Expenditure on rice = 25 × x = 25x
Expenditure of wheat = 9 × 5x = 45x
Total cost,
25x + 45x = 350
70x = 350
x = 5
Hence, price of Rice = ₦5 per kg.
Price of wheat = 25 per kg.
Now, price of wheat = 25 —- 20% ↑—-> ₦30 per kg.
Let the new amount of rice is N kg, then
N*5 + 9*30 = 350
N = 16 kg.
% decrease in the amount of rice
=(25−16)×100 / 25

=36%

12). The cost of packaging of the mangoes is 40% the cost of fresh mangoes themselves. The cost of mangoes increased by 30% but the cost of packaging decreased by 50%, then the percentage change of the cost of packed mangoes, if the cost of packed mangoes is equal to the sum of the cost of fresh mangoes and cost of packaging:

A. 14.17%

B. 7.14%

C. 8.87%

D. 6.66%

Correct Answers: B

Solution / Explanation:

Cost of fresh mangoes + Cost of packaging = Total cost
Let initial Cost of fresh, mangoes = 100
Then, packaging cost = 40
Thus, Initial total cost = 100 + 40 = 140
After increasing in cost of fresh mangoes 30%,
Cost of fresh mangoes = 130
And cost of packing go down by 50 % so,
Cost of packing = 20
Now Total cost = 130 + 20 = 150
Increased cost = 150 – 140 = 10
% increased = =10×100 / 140

=7.14%

13). An ant climbing up a vertical pole ascends 12 meters and slips down 5 meters in every alternate hour. If the pole is 63 meters high how long will it take it to reach the top?

A. 16 hours 35 min

B. 17 hours

C. 18 hours

D. 16 hours 40 min

Correct Answers: A

Solution / Explanation:

Since it climbs 7 meter in every 2 hr. At the end of 14 hours it would have climbed up to 49 mt. In 15th hour it will reach 61 mt. Then drops back to 56 mt in the 16th hour. It will take another 35 min to travel remaining 7 mt since it will be ascending in the 17th hour. Thus, 16 hr and 35 min.

Detail Explanation:
Given,
Ant ascends 12 meters in first hours and slips down 5 meters in second hour.
This is repeated in every alternate hour.
It means in every two hours Ant ascends (12 – 5 = 7 meters)

Therefore, in ends of 14 hours,
Ant ascends = 14×7 / 2 = 49 meters.
So, In next hour i.e 15 hour, Ant will ascends another 12 meter.
Till end of 15th hour, Ant climbed = 49 + 12 = 61 meters. But in 16th hour, Ant will slips down 5 meters (61 – 5 = 56 meters).
Remaining pole to climb,
= 63 – 56
= 7

A. 250 kmph

B. 500 kmph

C. 750 kmph

D. 1000 kmph

Correct Answers: D

Solution / Explanation:

By increasing the speed by 33.33%, it would be able to reduce the time taken for traveling by 25%.
But since this is able to overcome the time delay of 30 minutes, 30 minutes must be equivalent to 25% of the time originally taken.
Hence, the original time must have been 2 hours and the original speed would be 750 kmph.
Hence, the new speed would be 1000 kmph.

16). The sum of the ages of a daughter and her mother is 56 years. After 4 years, the age of the mother will be three times that of the daughter. At present their ages are?

A. 10 years, 46 years

B. 12 years, 44 years

C. 11 years, 45 years

D. 13 years, 43 years

Correct Answers: B

Solution / Explanation:

Let daughter’s age be x years.

Then, mother’s age = (56 −x) years

(56−x)+4 = 3(x+4)

⇒ 60−x = 3x+12

⇒ 4x = 48

⇒ x = 48 / 4

⇒ x = 12

Daughter’s age = 12 years
And the mother’s age = (56 − 12) = 44 years

Hence their ages are: 12 years, 44 years
