Answer 1

Answer:

a. 3000rs.

b.14 months

Step-by-step explanation:

firstly find the monthly salary of Rahul

24000/8 = 3000rs.

a. one year has 12 months

therefore, 12x3000=36000rs.

b. here let's suppose the number of months as y

thus, yx3000=42000

which is, y=42000/3000

y=14

therefore, the no. of months in which he earns 42000 is 14 months

Answer 2

Salary of one month = 24000 / 8
= ₹3000
a) Salary of 12 months = 12 x 300
= ₹36000
b) Number of months to earn ₹42000 = 42000 / 3000 = ₹14000
