$\huge{\underline{\underline{Question \::- }}}$

Sum of ages of a and b is 23 years and a is 3 years elder than b .
Then Find the ages of a and b .

$\huge{\underline{\underline{Answer \::- }}}$

♦ Given that

• Age of a + Age of b = 23

• Age of a = Age of b + 3

♦ Now by taking value of age of

a = b + 3

♦ Then

a + b = 23

$\implies (b+3) + b = 23$

$\implies 2b + 3 = 23$

$\implies 2b = 23 - 3$

$\implies 2b = 20$

$\implies b = \dfrac{20}{2}$

$\implies b = 10 \: years$

♦ Then From above

$\implies a + b = 23$

$\implies a + 10 = 23$

$\implies a = 23 - 10$

$\implies a = 13 \: years$

♦ Then ages of

a = 13 years

b = 10 years
