RRB Group-D Model Paper 12 with answers for online practice

Given:
Monthly income = Rs 2000
3 months income = 4 months expenditure
Formula used:
Income = Expenditure + Saving
Calculation:
According to the question,
4 months income of man = 4 × 2000 = 8000
And his expenditure of 4 months = 3 × 2000 = 6000
The money saved by the man in 4 months = 8000 - 6000 = 2000
∴ The money saved by the man in an year (12 months) = 3 × 2000 = Rs 600
