Answer 2

"

$\huge \frak \purple{b)12}$

Step-by-step explanation:

Q.

Last year, Shoaib was 4 times as old Basit. This year sum of their ages is 57. How old Basit now ?

.

Solution -

Let last year Basit's age = x,

his age this year = x + 1

Shoaib's age last year = 4×basut = 4x

his age this year = 4x + 1

.

Sum of their ages this year = 57

=> 4x + 1 + x + 1 = 57

=> 4x + x + 1 + 1 = 57

=> 5x = 57-2

=> 5x = 55

=> x = 55/5

=> x = 11

.

x = Basit's age last year = 11

his age this year = x + 1 = 11+1 = 12

.

hope it helps.
