Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeAn article is marked 20% above the cost price and with this a discount of 20% is also allowed on the article. If the selling price of the article is Rs 120, how much is the loss in the article?
Correct
Explanation:
SP = 120, discount is 20%, this means MP = (100/80)*120 = 150
MP is 20% above CP, so CP is (100/120)*150 = 125
So the loss is 125-120Incorrect
Explanation:
SP = 120, discount is 20%, this means MP = (100/80)*120 = 150
MP is 20% above CP, so CP is (100/120)*150 = 125
So the loss is 125-120 -

Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeA and B invested money in the ratio 4 : 5 in a business. They decided to give 10% of the total profit to charity. What is the total profit if B got Rs 2500 as his share?
Correct
Explanation:
Let x be profit, then (90/100)*x is divided among A and B in the ratio 4 : 5
So 5/9 * (90/100)*x = 2500
Solve, x = 5000Incorrect
Explanation:
Let x be profit, then (90/100)*x is divided among A and B in the ratio 4 : 5
So 5/9 * (90/100)*x = 2500
Solve, x = 5000 -
Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeThe ratio of the present ages of A and B is in the ratio 3 : 5. The ratio of A’s age 4 years ago and B’s age 2 years ago is 5 : 9. What is the age of A after 6 years?
Correct
Explanation:
3x and 5x
So (3x-4)/(5x-2) = 5/9
Solve, x = 13
So A’s present age = 3*13 = 39
After 6 years = 39+6Incorrect
Explanation:
3x and 5x
So (3x-4)/(5x-2) = 5/9
Solve, x = 13
So A’s present age = 3*13 = 39
After 6 years = 39+6 -

1 pointsCategory: Quantitative AptitudeAn amount of 4340 is obtained after 3 years on an investment of Rs 3500. What amount would have been retrieved if the rate of interest was 2% more?
Correct
Explanation:
Extra interest with 2% increased rate = 3500*2*3/100 = 210
So amount with 2% more interest = 4340+210Incorrect
Explanation:
Extra interest with 2% increased rate = 3500*2*3/100 = 210
So amount with 2% more interest = 4340+210 -

Question 7 of 10
7. Question
1 pointsCategory: Quantitative Aptitude10 men and 15 women can complete a work in 7 days. The same work can be completed by 11 men and 8 women in 10 days. What is the ratio of the daily work done by a man to that of a woman?
Correct
Explanation:
10m + 15w = 7
So 70m + 105w = 1
Also 11m + 8w = 10
So 110m + 80w = 1
So 70m + 105w = 110m + 80w
Solve, m/w = 5/8Incorrect
Explanation:
10m + 15w = 7
So 70m + 105w = 1
Also 11m + 8w = 10
So 110m + 80w = 1
So 70m + 105w = 110m + 80w
Solve, m/w = 5/8 -

Solve, x = 28
So SP = (110/100)*28Incorrect
Explanation:
20…………..……………32
………………x
32-x……………………x-20

Area of carpet = (315-5)*(225-5) = 68200 cm sq. = 6.82 m sq.
So cost = 6.82*1200Incorrect
Explanation:
leaving 2.5 cm space means 5 cm from length and breadth
Area of carpet = (315-5)*(225-5) = 68200 cm sq. = 6.82 m sq.
