Let us take pure milk contains 100 litre
20% replaced by water =>100*20/100=20
100-20=80
now 80 litre milk is available

Again 20% replaced by water =>80*20/100=16
80-16=64
now 64 litre milk is available

Again 20% replaced by water =>64*20/100=12.8
64-12.8=51.2
now 51.2 litre milk is available

The candles are lit simultaneously. They burn for 4+4+3+2=13 hours (till 3 candles extinguish).

Aatish Singh

• Feb 26th, 2015

Total Profit earned = 25% on 16/35 part = 1/4th of 16/35 = 4/35
Total Loss incurred = 10% on (1- 16/35th part - 3/7th part) = 1/10 of 4/35th part = 4/350
Hence total profit = 4/35-4/350 = 4/35 * 9/10 = 36/350= 10.2%

The age of the father is 18 years older to his son. After 5 years fathers age becomes thrice of his son, What is fathers present age.

Vasu Sachdeva

• Jul 7th, 2017

Present age of father is 22 years
as father is 22 years so son is 22-18=4 years
after 5 years father is 27 and son becomes 9 year which makes father thrice age of his son

suman

• May 21st, 2016

Let Sons present age = x years
so, fathers present age = x+18 years
after 5 years, sons age will be = x+5 years
fathers age will be = x+23 years
according to the problem,
x+23 = 3 (x+5)
or, 2x=8
or, x=4
so, fathers present age is (4+18) years = 22 years

First Race=x
Second Race= x+6
Total = Rs. 68
x+(x+6)=68

2x=68-6
2x=62
x=62/2

First race=Rs. 31
Second race= 31+6= Rs. 37
