Question

John had 250rs . he spent 50rs on books, find his percent expenditure.

Answer 1

Answer:

20%

Step-by-step explanation:

At first we have to find the fraction

1.From a total of 250 rs he spent 50 rs therefore the fraction would be 50/250(expenditure/total) which is 1/5

2. To find the percentage figure just multiply it by 100

So 1/5 *100 which is 20%

Answer 2

Answer:

60%*100/150=90

science marks = 90-3= 87
