∴ Present age of son = x + 5

RRB Group D Mock Test - 9 - Question 3

If 2x+y=17,y+2z=15 and x+z=9 then what is the value of 4x+3y+z?

Detailed Solution for RRB Group D Mock Test - 9 - Question 3

2x + y = 17, y + 2z = 15 and x + z = 9
⇒ z = 9 - x
∴ y + 2(9 - x) = 15
or y + 18 - 2x = 15
or y - 2x = -3
y + 2x = 17
⇒ 2y = 14
⇒ y = 7
⇒ 2x + 7 = 17 ⇒ x = 5
z + 5 = 9 ⇒ z = 4
∴ 4x + 3y + 2 = 4 x 5 + 3 x 7 + 4
= 20 + 21 + 4 = 45
