Baichung's father is 26 years younger than Baichung's grandfather and 29 years older than Baichung. The sum of the ages of all the three is 135 years. What is the age of each one of them? years and Baichung's granddaughter's age = (x+29+26)=(x+55) years.
Let x be the number of winners.
Then the number of participants who do not win is given as (63 – x)
The prize money given to x winners = Rs ( 100x)
The prize money given to (63 – x) participants is = Rs 25(63 – x)
According to the given data, the total prize money distributed = Rs 3000
Therefore, 100x + 25(63 – x) = 3000
4x + (63 – x) = 120
3x + 63 = 120
x = 19
Therefore, the number of winners is 19.
