Question

20 year before age of lucy 4 times more than bani. sum of present age is 95 . what is bani present age

Answer 1

Answer:

Lucy's age = 64, Bani's age = 31

Step-by-step explanation:

Let Lucy's present age be x and Bani's present age be y

Then,

condition 1 :

(x - 20) = 4×(y - 20)

x - 4y = -60

condition 2 :

x + y = 95

eqn 1 - eqn 2:

-5y = -155

y = 31

x = 95 - 31

x = 64
