Question 192
At present Sofia is 1.5 times Shalu’s age and twice Saloni’s age. After six years Sofia will be 1.4 times Shalu’s age and Satoni will be 0.8 times Shalu’s age then. What is Salonfs present age
Solution
Let Sofia's present age be x
Let Shalu's present age be y
Let Saloni's present age be z
From given conditions,
x = 1.5y = 2z
x+6 = 1.4(y+6)
z+6 = 0.8(y+6)
x= 2z and y =4z/3
Substituting these conditions, we get z = 18
