Question

Arun gave his sister 40 % of his pocket money and was left with Rs. 8. What is his pocket money (in Rs.)?

Answer 1

Answer: Rs. 13.34

Step-by-step explanation:

Let the amount of pocket money Arun gets be Rs. “x” .

He gave 40% of his pocket money to his sister, so, he gave

= [40/100] * x

= 0.4x

∴ Money left with him = [x – 0.4x]

But, we are given after giving his sister he is left with Rs. 8.

Therefore, the equation becomes

x – 0.4x = 8

⇒ 0.6 x = 8  

⇒ x = 8/0.6 = Rs. 13.34

Thus, the amount Arun gets as his pocket money is Rs. 13.34.

Answer 2

Answer:

The correct answer is 13.33 rupees

Step-by-step explanation:

According to the question 60%= 8 rupees

60% means 60/100=0.6

if we find the number which is multiplied with 0.6 then the total pocket money will be calculated

so 0.6*x=8 rupees

x=8/0.6=80/6=13.33

so the total amount is 13.33 rupees and 8 rupees is the 60% of 13.33 rupees
