Given: R = 0.4 × (S + R)
= Rs 42000
Syam = Saves 70% of income
Savings R + S = 60% of income
Calculation: Let X be total income
Total expense by ram and shyam = (100 – 60)% of X
⇒ Total expense by ram and shyam = 42000 × 2
⇒ 84000 = 40 ×
⇒ X = Rs 2,10,000
Salary of ram = 0.4 × Total Salary of shyam and Shyam
⇒ Salary of ram = 0.4 × 2,10,000
⇒ Salary of ram = 84000
Salary of Shyam = 210000 - 84000
⇒ Salary of Shyam = 126000
⇒ Required difference = 126000 - 84000
⇒ Required difference = 42000
∴ Required difference is Rs 42000.
