Question

rakesh gets salary of rs.40,000 per month, his salary increases by 8% every year. find his monthly salary after 2 years​

Answer 1

Answer:

Initial Saving = Rs 10000

Step-by-step explanation:

Income = 40000

Increased income = 40000 * (1.08) = 43200

Let initial expenditure = 100x

Initial Saving = 40000-100x

Later expenditure = 112x ( increased by 12 %)

Later Saving = (40000-100x)(0.96)    Decrased by 4 %

Later Saving = Later income - Later Expenditure

Later Saving = 43200 - 112x

43200 - 112x = (40000-100x)(0.96)

43200 - 112x = 38400-96x

4800 = 16x

x = 300

100x = 30000

Initial saving = 40000 - 100x = 40000-30000 = 10000
