Twenty-four men can complete a work in 18 days and twenty women can complete the same work in 16 days. Thirty-six men started the work and left after 3 days. Now ten women started the work and left after 4 days. What amount of left is completed by now?

Correct

Explanation:
24m in 18 days, so 36 in 24*18/36 = 12 days
In 3 days, they did 1/12 * 3 = 1/4 work
20w in 16 days, so 10 in 20*16/10 = 32 days
In 4 days, they did 1/32 * 4 = 1/8 work
So completed work = 1/4 + 1/8

Incorrect

Explanation:
24m in 18 days, so 36 in 24*18/36 = 12 days
In 3 days, they did 1/12 * 3 = 1/4 work
20w in 16 days, so 10 in 20*16/10 = 32 days
In 4 days, they did 1/32 * 4 = 1/8 work
So completed work = 1/4 + 1/8

A box contains 250 tickets (numbered 1 to 250). Find the probability of drawing a ticket containing a multiple of 4 or 7.

Correct

Explanation:
Multiple of 4 up to 250 = 250/4 = 62
Multiple of 7 up to 250 = 250/7 = 35
Multiples of 4*7 = 28 up to 250 = 250/28 = 8
So required probability = (62+35 – 8)/250

Incorrect

Explanation:
Multiple of 4 up to 250 = 250/4 = 62
Multiple of 7 up to 250 = 250/7 = 35
Multiples of 4*7 = 28 up to 250 = 250/28 = 8
So required probability = (62+35 – 8)/250

An article is marked 25% above the cost price and it gets a 10% discount also. Find the profit percent if the seller cheats while selling by using 10% less weight.

Correct

Explanation:
Let CP = 100
So MP = 125
So SP after discount = 90/100 * 125 = 112.5
Now seller selling 10% less in weight so CP = Rs 90
Now CP = 90, SP = 112.5
So profit % = 22.5/90 * 100

Incorrect

Explanation:
Let CP = 100
So MP = 125
So SP after discount = 90/100 * 125 = 112.5
Now seller selling 10% less in weight so CP = Rs 90
Now CP = 90, SP = 112.5
So profit % = 22.5/90 * 100

A and B started a business with investments Rs 1800 and Rs 2400 respectively. After 6 months, C also joined them with investment of Rs 4000. If after a year a total of Rs 42,000 is earned as profit, what is the share of C?

Correct

Explanation:
A : B : C
1800*12 : 2400*12 : 4000*6
9 : 12 : 10
10/(9+12+10) * 42,000 = 13548

Incorrect

Explanation:
A : B : C
1800*12 : 2400*12 : 4000*6
9 : 12 : 10
10/(9+12+10) * 42,000 = 13548

A rectangular box has length, breadth and height in the ratio 7 : 2 : 7. These are respectively increased by 20%, 5% and 50%. What is the approximate decreased percentage in volume of rectangular box?

Correct

Explanation:
7x, 2x and 7x, so volume = 98x^{3}
Now when increase is done, ratio is
(120/100)*7x : (105/100)*2x : (150/100)*7x
4 : 1 : 5, so volume = 20x^{3}
% increase = (98-20)/98 * 100 = 20%

Incorrect

Explanation:
7x, 2x and 7x, so volume = 98x^{3}
Now when increase is done, ratio is
(120/100)*7x : (105/100)*2x : (150/100)*7x
4 : 1 : 5, so volume = 20x^{3}
% increase = (98-20)/98 * 100 = 20%
