Correct
Explanation:
4 w = 2m, so 1w = 1/2 m
And then 20 w = 10 m, so we have to find the number of days for 10 men to complete remaining work (1 – 2/5) = 3/5th.
M1*D1*H1*W2 = M2*D2*H2*W1
20*10*6*(3/5) = 10*D2*4*(2/5)
Solve, D2 = 45 daysIncorrect
Explanation:
4 w = 2m, so 1w = 1/2 m
And then 20 w = 10 m, so we have to find the number of days for 10 men to complete remaining work (1 – 2/5) = 3/5th.
M1*D1*H1*W2 = M2*D2*H2*W1
20*10*6*(3/5) = 10*D2*4*(2/5)
Solve, D2 = 45 days 
Question 79 of 100
79. Question
1 pointsCategory: Quantitative AptitudeIn a pack of 8 items, 2 items which costs Rs 21 and Rs 23 respectively are replaced by two new items. If the average cost of the pack increased by Rs 2, what is the average cost of the two new items added?
Correct
Explanation:
Average of 8 items increased by 2, this means the total cost of pack increased by 8*2 = 16 yrs
So sum of cost of two new items = 21+23+16 = 60
Average of these = 60/2Incorrect
Explanation:
Average of 8 items increased by 2, this means the total cost of pack increased by 8*2 = 16 yrs
So sum of cost of two new items = 21+23+16 = 60
Average of these = 60/2

1 pointsCategory: Quantitative AptitudeA and B have their present ages in the ratio 5 : 3. Also A’s age 4 years ago and B’s 4 years hence is same. Find the ratio of A’s age 2 years hence to B’s age 2 years ago.
Correct
Explanation:
Let A’s present age = 5x, and B’s = 3x
A’s age 4 years ago to B’s age 4 years hence is same
So (5x4) = (3x+4)
Solve x = 4
So A’s present age = 20, and B’s = 12
Required ratio = (20+2) : (122)Incorrect
Explanation:
Let A’s present age = 5x, and B’s = 3x
A’s age 4 years ago to B’s age 4 years hence is same
So (5x4) = (3x+4)
Solve x = 4
So A’s present age = 20, and B’s = 12
Required ratio = (20+2) : (122)

Correct
Explanation:
P = 1248*100/[r1*t1 + r2*t2 + r3*t3]
P = 1248*100/[3*3 + 6*4 + 9*5]Incorrect

1 pointsCategory: Quantitative AptitudeA trader allows a discount of 30% on the market price of an article, and then also gains 40% on it. What is the profit % of the trader if the article is sold allowing no discount?
Correct
Explanation:
Let MP = Rs 100
30% discount so SP = Rs 70, then Discount = 30
Gain = 20%
CP = (100/140) * 70 = 50
No discount means SP = MP
So Profit% when no discount = [10050/50]*100Incorrect
Explanation:
Let MP = Rs 100
30% discount so SP = Rs 70, then Discount = 30
Gain = 20%
CP = (100/140) * 70 = 50
No discount means SP = MP
So Profit% when no discount = [10050/50]*100

83. Question
1 pointsCategory: Quantitative AptitudeA certain amount retrieved Rs 562.5 as simple interest when invested at the rate of 6% per annum for 5 years. Had the same amount be invested at 4% per annum compounded annually, what would be the compound interest obtained after 2 years.
Correct
Explanation:
562.5 = P*6*5/100
So principal = Rs 1875
CI = 1875 [(1 + 4/100)^2 – 1]
= 1875 [676/625 – 1]Incorrect
Explanation:
562.5 = P*6*5/100
So principal = Rs 1875
CI = 1875 [(1 + 4/100)^2 – 1]
= 1875 [676/625 – 1]

Correct
Explanation:
Given: 3P = P [1 + r/100]^2
Raise to power 4 both sides gives
[3P]^4 = {P [1 + r/100]^2}^4
81 = [1 + r/100]^8 – so 8 yearsIncorrect
Explanation:
Given: 3P = P [1 + r/100]^2

1 pointsCategory: Quantitative AptitudeThe area of a circle having diameter 14 m equals the area of rectangle. If the length of rectangle is 8 less than twice the breadth, what is the perimeter of rectangle?
Correct
Explanation:
Ar of rect. = (22/7) *7 * 7 = 154
So (2b8)*b = 154
So 2b^2 – 8b – 154 = 0
Or b^2 – 4b – 77 = 0
Solve, b = 11, so l = 2b8 = 14
So perimeter = 2(11+14)Incorrect
Explanation:
Ar of rect. = (22/7) *7 * 7 = 154
So (2b8)*b = 154
So 2b^2 – 8b – 154 = 0

94. Question
1 pointsCategory: Quantitative AptitudeA person saves 16 2/3% from his salary of Rs 7800. How much did he spend?
Correct
Explanation:
16 2/3 = 50/3 saved, so (100 – 50/3)% spend = 250/3%
So spend money = (250/3)/100 * 7800 = 250*7800 / 300Incorrect
Explanation:
16 2/3 = 50/3 saved, so (100 – 50/3)% spend = 250/3%
So spend money = (250/3)/100 * 7800 = 250*7800 / 300
