A is 25% more efficient than B. If B alone can finish a work in 15 days, in how many days can A and B together finish it?
सही उत्तर: ग) 6 2/3 days
A takes 15/1.25 = 12 days. Together: 1/12 + 1/15 = 9/60, so time = 60/9 = 6 2/3 days.

A alone can do a job in 6 days and B alone in 12 days. With the help of C they finish it in 3 days and receive Rs. 3,000 in all. What is C's share?
सही उत्तर: घ) Rs. 750
In 3 days A does 3/6 = 1/2 and B does 3/12 = 1/4 of the work, so C does 1/4. C's share = 1/4 × 3000 = Rs. 750.

A can do a work in 18 days and B in 24 days. They start together, but A leaves 3 days before the work is finished. In how many days is the work completed?
सही उत्तर: ग) 12 days
If the work takes t days, A works (t − 3) days: (t − 3)/18 + t/24 = 1, i.e. 4(t − 3) + 3t = 72, so 7t = 84 and t = 12.

Ram is twice as old as Shyam was when Ram was as old as Shyam is now. If Ram is 40 years old now, how old is Shyam?
सही उत्तर: ग) 30 years
Let Shyam be S; Ram was S years old (40 − S) years ago, when Shyam was S − (40 − S) = 2S − 40. So 40 = 2(2S − 40), giving S = 30.

Four years ago the ratio of the ages of A and B was 3 : 4. Four years hence it will be 5 : 6. What is B's present age?
सही उत्तर: क) 20 years
Ages 4 years ago: 3x and 4x. Then (3x + 8)/(4x + 8) = 5/6 gives 18x + 48 = 20x + 40, so x = 4. B now = 4x + 4 = 20 years.

The average salary of all workers in a workshop is Rs. 8,000. The average salary of 7 technicians is Rs. 12,000 and that of the rest is Rs. 6,000. How many workers are there in total?
सही उत्तर: क) 21
7 × 12000 + (n − 7) × 6000 = 8000n gives 84000 − 42000 = 2000n, so n = 21.
