Question

Sum of the present ages of Ram and Raju is 31.3 years ago Ram's age was 4 time the age of Raju Find their present ages

Answer 1

Answer:

Let the present age of Ram and Raju be x and y respectively.

Therefore,x+y=31...............(1)

Three years ago,

Ram's age=x-3

Raju's age=y-3

Therefore,(x-3)=4(y-3)

x-3=4y-12

x-4y=-12+3

x-4y=-9.........(2)

Subtracting (1) and (2),

x+y-x+4y=31+9

5y=40

y=8

Putting y value in (1)

x+8=31

x=31-8

x=23

Ram's age=x=23

Raju's age=y=8

Answer 2

Let present age of ram = x
Present age of raju = y
ATQ
X + Y = 31
X = 31 - y
3years ago
4 (Y -3) = x - 3
4y -12 = 31- y-3
5y = 31 + 9
5y = 40
Y = 8 years
Present age of raju = 8 years
Present age of ram (x) = 31-8
= 23 years
