Question

solve the following word problem​

Answer 1

Let the age of Rupali be x and age of Dipali be y

then x+ y = 29..... (1)

But rupali is 3 yrs younger than Dipali thus x = y - 3 .....(2)

Putting (2) in (1)we get

y - 3 + y = 29

2y = 32

y = 16

Putting value of y in (1) We get

x + 16 = 29

x = 13

Thus the age of Rupali is 13 and the age of Dipali is 16

Answer 2

Answer by Rashid21

Given : The sum of the age of Rupali and Dipali is 29 years , Rupali is 3 years younger than Dipali.

To Find : Rupali and Dipali Present age

Soluⁿ : Suppose the age of Rupali and Dipali are 'x' and 'y' respectively.

so, According to the first condition ;

x + y = 29 .....(1)

Now, According to second condition ;

x = y–3

x–y = –3 ......(2)

Solving Equations (1) and (2) ;

x + y = 29

x – y = –3

___________

2x = 26

x = 13

substitute the value of x in eqⁿ (1)

y = 29 – 13

y = 16

Ans. Hence the age of Rupali and Dipali are 13 and 16 Respectively.
