Category: Quantitative Aptitude

A certain sum of money amounts to Rs 812 in 2 yrs and to Rs 896 in 3.5 yrs. Find the sum and the rate of interest.

Correct

Explanation:
SI for 1.5 yrs = 896 – 812 = Rs 84
So, for 2 yrs SI = 84/1.5 * 2 = Rs 112
Amount for 2 yrs is 812, so P = 812 – 112 = Rs 700
This gives, r = 100*112/(700*2) = 8%

Incorrect

Explanation:
SI for 1.5 yrs = 896 – 812 = Rs 84
So, for 2 yrs SI = 84/1.5 * 2 = Rs 112
Amount for 2 yrs is 812, so P = 812 – 112 = Rs 700
This gives, r = 100*112/(700*2) = 8%

In an alloy weighing 10 kg, 1/4th is nickel and the rest is copper. It is mixed with an alloy weighing 7 kg in which 1/2 is nickel and the rest is copper. What is the ratio of nickel to copper in the final mixture?

Correct

Explanation:
After mixing the two, quantity of nickel = 1/4 * 10 + 1/2 * 7 = 6
Quantity of copper = 3/4 * 10 + 1/2 * 7 = 11
Ratio of nickel to copper = 6 : 11

Incorrect

Explanation:
After mixing the two, quantity of nickel = 1/4 * 10 + 1/2 * 7 = 6
Quantity of copper = 3/4 * 10 + 1/2 * 7 = 11
Ratio of nickel to copper = 6 : 11

In an examination it is required to get 350 marks of the aggregate marks to pass. A student gets 30.2% marks and is failed by 42 marks. Find the maximum aggregate marks a student can get.

Correct

Explanation:
He got failed by 42 marks so has received (350-42) = 302 marks which is equal to 30.2% of aggregate marks
So 30.2% of aggregate marks = 302
aggregate marks = 30200/30.2 = 1000

Incorrect

Explanation:
He got failed by 42 marks so has received (350-42) = 302 marks which is equal to 30.2% of aggregate marks
So 30.2% of aggregate marks = 302
aggregate marks = 30200/30.2 = 1000

In which year is the percentage increase in the number of students over the previous year the highest for taking part in painting?

Correct

Explanation:
In 2012, 2013 the number is decreasing
For other years it can be seen that in 2011, the increase is very high, so % will also be high as compared in other years.
It is not always applicable. Since the difference between 2600 and 1800 is much high then the difference between other years.
