Solution

We know the $p i e$ $c h a r t = 360 ° .$
$P + Q + R + S = 360 °$
$120 ° + 96 ° + 60 ° + S = 360 °$
$276 ° + S = 360 °$
$∴ S = 84 °$
$P = 100$ $l a k h$
$∴ \frac{120}{360} \times x = 100$ $l a k h$ .
$∴$ Total populatino of all $4$ cities is $300$ $l a k h,$ then population in $S = \frac{84}{360} \times 300 = 70$ $l a k h .$
