Correct Answer - Option 2 : 14
Given:
Saving of Suman = \(33\frac{1}{3}\)%
expenditure increased by 10%
Saving increase by 22%
Concept:
Saving = Income – Expenditure
Solution:
Let the income of Suman be 300 unit
⇒ Saving of Suuman = 100/(3 × 100) × 300
⇒ 100 unit
Saving = Income – Expenditure
⇒ 100 = 300 – Expenditure
⇒ Expenditure = 200 unit
According to question
Saving = Income – Expenditure
⇒ 100 + (100 × 22)/100 = 300 + (300 × x)/100 – (200 + (200 × 10)/100)
⇒ 122 = 300 + (300 × x)/100 – 220
⇒ 122 + 220 – 300 = (300 × x)/100
⇒ (42 × 100)/300 = x
⇒ x = 14
∴ The value of x is 14
