Anish has got how much percent more than Kashish?

Correct

Explanation:
Total marks of Anish = 80+70+80+100+80+40 = 450
So his % = 450/600 * 100 = 75%
Total marks of Kashish = 80+80+35+65+50+75 = 385
So his % = 385/600 * 100 = 64%
So 75 – 64

Incorrect

Explanation:
Total marks of Anish = 80+70+80+100+80+40 = 450
So his % = 450/600 * 100 = 75%
Total marks of Kashish = 80+80+35+65+50+75 = 385
So his % = 385/600 * 100 = 64%
So 75 – 64

Question 8 of 10

8. Question

1 points

Category: Quantitative Aptitude

Three friends A, B and C divide Rs 4500 among them such that A and B get the money in the ratio 1 : 4 and B and C get in the ratio 2 : 5 respectively. If to all their shares, Rs 600 is added, what will be the new ratio of dividing the total money among them?

Correct

Explanation:
A/B = 1/4 and B/C = 2/5
So A : B : C = 1*2 : 4*2 : 4*5 = 2 : 8 : 20 = 1 : 4 : 10
A got = [1/(1+4+10)] * 4500 = 300, B got = [4/(1+4+10)] * 4500 = 1200, C got = [10/(1+4+10)] * 4500 = 3000
When 200 is added to their shares, A gets=300+600 = 900, B = 1800, C =3600
So new ratio is 900 : 1800 : 3600

Incorrect

Explanation:
A/B = 1/4 and B/C = 2/5
So A : B : C = 1*2 : 4*2 : 4*5 = 2 : 8 : 20 = 1 : 4 : 10
A got = [1/(1+4+10)] * 4500 = 300, B got = [4/(1+4+10)] * 4500 = 1200, C got = [10/(1+4+10)] * 4500 = 3000
When 200 is added to their shares, A gets=300+600 = 900, B = 1800, C =3600
So new ratio is 900 : 1800 : 3600

Question 9 of 10

9. Question

1 points

Category: Quantitative Aptitude

A, B and C can alone complete a work in 10, 15 and 25 days respectively. They all started the work. A and B left the work after 3 days and C completed the remaining work. How many extra days will be taken to complete the work now?

Correct

Explanation:
If all worked for all the days, then (1/10 + 1/15 + 1/25) = 31/150
So they would have completed in 150/31 days.
But they worked for 3 days, so work completed is (31/150)*3 = 31/50
Work left = 1 – 31/50 = 19/50 which is to be completed by C
C completes 1 work in 25 days, so 19/50 work in (19/50)*25 = 19/2 days
So total work completed in 3+(19/2) = 25/2 days
Extra days taken = 25/2 – 150/31

Incorrect

Explanation:
If all worked for all the days, then (1/10 + 1/15 + 1/25) = 31/150
So they would have completed in 150/31 days.
But they worked for 3 days, so work completed is (31/150)*3 = 31/50
Work left = 1 – 31/50 = 19/50 which is to be completed by C
C completes 1 work in 25 days, so 19/50 work in (19/50)*25 = 19/2 days
So total work completed in 3+(19/2) = 25/2 days
Extra days taken = 25/2 – 150/31
