Answer:
Step-by-step explanation:
Present age of ramesh= x years
Present age of mahesh = y years
Present age of Amit = 93-(x+y)
According to given condition
x-10/y-10=2/3
It gives
3x-30=2y-20
3x-2y=10.................... equation 1
According to the condition
y-10/93-(x+y)-10= 3/4
y-10/83-x-y = 3/4
It gives
4y-40=249-3x-3y
3x+4y+3y=249+40
3x+7y=289.................... equation 2
Substract equation 1&2
3x+7y=289
- 3x -2y=10
And:- 9y=279
y=279/9
y =31
Put y =31 in equation 1
3x-2×31=10
3x-62=10
3x =72
x=72/3
x=24
Present age of ramesh=24yrs
Present age of mahesh = 31 yrs
Present age of amit = 93-(24+31)
= 93-55
= 38
