What annual installment will discharge a debt of Rs 6000 due in 5 years at 10% per annum simple interest?

Correct

Explanation:
I = 100A/ [100t + rt(t-1)/2]
So I = 100*6000/ [100*5 + 10*5*(5-1)/2] = 100*6000/ [500 + 100]

Incorrect

Explanation:
I = 100A/ [100t + rt(t-1)/2]
So I = 100*6000/ [100*5 + 10*5*(5-1)/2] = 100*6000/ [500 + 100]

When a bus drove at 55 km/hr from bus stop, it reached school 20 minutes late and when the same bus drove at 60 km/hr, it reached school 15 minutes earlier. What is the distance between bus stop and school?

Correct

Explanation:
Difference in time = 20 – (-15) = 35 minutes or 35/60 hr
Distance = Product of speeds/Difference of speeds * Difference in time
i.e. [60*55/(60-55)] * 35/60

Incorrect

Explanation:
Difference in time = 20 – (-15) = 35 minutes or 35/60 hr
Distance = Product of speeds/Difference of speeds * Difference in time
i.e. [60*55/(60-55)] * 35/60

A and B invested in a business as Rs 3000 and Rs 3500 respectively. After 4 months A added Rs 3000 more and B invested amount such that it became equal to which A has invested now as total. If after a year, B gets Rs 9610 as his share of profit, what is the total profit?

In how many ways all the letters of the word ‘ASSISTANT’ be arranged such that all vowels are together?

Correct

Explanation:
Take vowels in a box together as one – A, I, A other are S, S, S, T, N, T
So there are 7 that to be placed for this 7!, now there are 3 S and 2 T so 7!/(3! * 2!)
Now inside box, there are 3 vowels with 2 A, so there arrangement = 3!/2!
So total = 7!/(3! * 2!) * 3!/2!

Incorrect

Explanation:
Take vowels in a box together as one – A, I, A other are S, S, S, T, N, T
So there are 7 that to be placed for this 7!, now there are 3 S and 2 T so 7!/(3! * 2!)
Now inside box, there are 3 vowels with 2 A, so there arrangement = 3!/2!
So total = 7!/(3! * 2!) * 3!/2!

The difference in the ages of Raghav and Sumit is 7 years. The ratio of ages of Sumit before 4 years and Raghav after 4 years is 7 : 12. What is the sum of their present ages?

Correct

Explanation:
R – S = 7
(S-4)/(R+4) = 7/12
Solve both equations, S = 25, R = 32, so sum = 25+32

Incorrect

Explanation:
R – S = 7
(S-4)/(R+4) = 7/12
Solve both equations, S = 25, R = 32, so sum = 25+32

Find the least number which when divided by 2, 7, 10 and 15 leaves a remainder 8 but leaves no remainder when same number is divided by 11.

Correct

Explanation:
LCM(2, 7, 10, 15) = 210
So the number will be somewhat = 210x + 8
This number leaves no remainder when divided by 11, so x = 3 to get (210x+8) fully divided by 11
So number = 210*3 + 8

Incorrect

Explanation:
LCM(2, 7, 10, 15) = 210
So the number will be somewhat = 210x + 8
This number leaves no remainder when divided by 11, so x = 3 to get (210x+8) fully divided by 11
So number = 210*3 + 8

20 men and 25 women can complete a work in 8 days. The same work can be completed by 30 women and 16 men in 7 days. What is the ratio of the daily work done by a man to that of a woman?

Correct

Explanation:
20m + 25w = 8
So 160m + 200w = 1
Also 16m + 30w = 7
So 112m + 210w = 1
So 160m + 200w = 112m + 210w
Solve, m/w = 5/24

Incorrect

Explanation:
20m + 25w = 8
So 160m + 200w = 1
Also 16m + 30w = 7
So 112m + 210w = 1
So 160m + 200w = 112m + 210w
Solve, m/w = 5/24

By selling 100 articles, a tradesman makes a loss equal to the cost price of 18 articles. Find his loss%.

Correct

Explanation:
C.P of 100 articles – S.P of 100 articles = C.P of 18 articles
C.P of 82 articles = S.P of 100 articles
loss% = [(100 – 82)/100] * 100 = 18%

Incorrect

Explanation:
C.P of 100 articles – S.P of 100 articles = C.P of 18 articles
C.P of 82 articles = S.P of 100 articles
loss% = [(100 – 82)/100] * 100 = 18%
