• 100 liters of a mixture of Boric Acid and water contains 80% Boric Acid. So what amount of water should be added to the mixture to reduce the strength of Boric Acid in the mixture to 50%?

Page 70: Advanced Accountancy 29 Sept

www.afterschoool.tk AFTERSCHO☺OL's MATERIAL FOR PGPSE PARTICIPANTS

Solution

• Total liquid = 100 liters• Boric acid = 80 liters• We have to make it 50%, so the total liquid

should be 160 (just double of it). That means we have to add 160-100 = 60 liters of water.

piece of work in 24.days each of 9 hours, then find how many men with the help of 4 women and 5 boys can finish the work in 18 days each of 6 hours.

• We know that (A –B)^2 = A^2 – 2AB+ B^2• A = 16/7• B= 9/7, solutoin is 1. (16 -7 = 7,so 7/7) • Thus the above equation is just expansion

of this equation. Thus the value of * is 2AB, out of which we already have B. thus the remaining number is 2A = 32/7, we already have 7, thus answer is 32.

www.afterschoool.tk AFTERSCHO☺OL's MATERIAL FOR PGPSE PARTICIPANTS

Solution • For the first 2 days – A and B are working

together… (2*1/8) + (2* 1/9) = 34/72• Now A,B,C will work together: • 1/8 +1/9 + 1/6 = 29/72• They will complete the work in 72/29 • Now multiply this by (1- 34/72) * 72/29• (because 34/72 work is already complete, the

remaining work is 38/72) • =38/72 *72/29 = 38/29. • Thus total time required is 2 +38/29 answer.

A is twice as good a workman as B; and together they finish

a work in 14 days. In how many days can it be done by each

separately?

• Let us assume that A takes X and B takes 2X days. 1/2x + 1/x = 1/14

• Let us assume 1/x = Y• Y/2 + Y = 1/14• 3/2Y = 1/14 or Y = 2/42 or 1/21• Thus A can do it in 21 days and B in 42 days.

days before the completion of work. In how many days would

the work have been completed?

Page 150: Advanced Accountancy 29 Sept

www.afterschoool.tk AFTERSCHO☺OL's MATERIAL FOR PGPSE PARTICIPANTS

Solution

• For 2 days only A and B worked• 2/20 + 2/20 = 4/20 or 1/5• Together (all three) : • 1/20+1/20+1/40 = (2+2+1) / 40 = 1/8• Thus they take 8 days to complete the

work, but they completed only 4/5 work together, so 8*4/5 = 6.4 days were taken by them. Thus total days : 8.4 days. Answer.
