In a particular year, the average monthly expenditure of Vipin was ₹6,250 during the first 4 months, ₹6,500 during the next 4 months, and ₹x during the remaining months of the year. If his total savings in the year were ₹15,000 and his monthly salary was ₹9,600, then find the value of x.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ₹12,300
Given that
Vipin's total saving in the year was ₹15,000
⇒His total expenditure in the year = ₹6,250 × 4 + ₹6500 × 4 + ₹x × 4 = ₹(51000 + 4x)
His monthly salary was ₹9,600
then his salary in the year was 9600 × 12 = ₹115200
As we know,
Expenditures = Income - Savings
⇒₹(51000 + 4x) = ₹115200 - ₹15,000 = ₹100200
⇒4x = ₹49200
x = ₹12,300
