Answer 1

Answer:

$let \: the \: age \: of \: amna \: be \: x \\ let \: the \: age \: of \: maryam \: be \: x - 5 \: \\ let \: age \: of \: sana \: be \: x - 9 \\ sum \: of \: their \: age \: is \: 50 \\ so \: x + x- 5 + x- 9 = 50 \\ 3x + ( - 14) = 50 \\ 3x - 14 = 50 \\3 x = 50 - 14 \\ 3 x = 36 \\ x= \frac{36}{3} \\ x = 12 \: \\ age \: of \: amna \: is \: 12 \\ age \: of \: maryam \: is \: 12 - 5 = 7 \\ the \: age \: of \: sana \: is \: 12 - 9 = 3$
