Explanation

If a sum becomes 3 times in x years, and you're using compound interest, then:

• In 2x years, it becomes $3\times 3=9$ time

• In 3x years, it becomes $3\times 3\times 3=27$ time

So, if the sum triples in 4 years, it becomes 27 times in $4\times 3=12$ years.

Explanation

Work done by 12 men in 4 days = 1 (full work)

Work done by 1 man in 4 days = 1/12

Work done by 6 men in 4 days = 6/12 = 1/2 (i.e., half of the work)

Work done by 6 men in 2 days = (1/2) × (2/4) = 1/4

Remaining work = 1 - 1/4 = 3/4

15 women complete the full work in 4 days → 1 woman’s 1-day work = 1/(15 × 4) = 1/60

Work needed in 3 days → x women × 3 × (1/60) = 3/4

x = (3/4) × (60/3) = 15 women
