please answer the question
and the answer sheet for helpful =madan=10,mohan=6
Answers
Answer:
Let Mohan's age be x years and Madan's age be y years.
Ages before 4 years,
Mohan = ( x - 4 )
Madan = ( y - 4 )
By the 1st condition,
x + y = 16 ............................1
By the 2nd condition,
( y - 4 ) = 3 × ( x - 4 ) y - 4.
= 3x - 12
y. = 3x - 12+4
y - 3x = - 8
3x-y. = 8..........................2
Adding eq 1 and eq 2 ,
x + y = 16
+
3x -y = 8
4x. = 24
x = 24
4
x = 6
Now,
Substituting ( x = 6 ) in eq 1 ,
x + y = 16
6 + y = 16
y = 16 - 6
y = 10
But,
Mohan's age = x = 6years
Madan's age = y = 10years
I hope it will help you
Step-by-step explanation:
according to the situation 1:
let madan's be x
let madan's be xand mohan's age be y
let madan's be xand mohan's age be ySum of age of Madan and Mohan is 16
x+y=16
x+y=16-4-4=8
according to the situation 2:
four years back
four years backlet madan's be x-4
four years backlet madan's be x-4and mohan's age be y-4
(x-4)=4(y-4)
x=4y-16+4
x=4(y-3)
x=4(y-3)
put the value of x in situation 1:
4(y-3)+y=8
4y+y-12=8
5y=12+8=20
y=20/5=4
:. Mohan's age is 4
and Madam's age is 12
