Question
Sonal had a total income of Rs. 45000. She spent Rs. 5000 less than the amount she saved. What portion of her income did she spend in percentage?
Solution
ATQ,
Let the amount saved by Sonal = Rs. Y
Then, amount spent by Sonal = Rs. (Y - 5000)
We have, Y + Y - 5000 = 45000
Or, Y = (45000 + 5000) ÷ 2 = Rs. 25000
So, amount spent by Sonal = 25000 - 5000 = Rs. 20000
Required percentage = (20000 / 45000) × 100 = 44.44%
