According to the question,
(P + q + r + s + t) /5 = 28
Or, p + q + r + s + t = 28 * 5 = 140. .......(1)
Again, it is given that,
(P + r + t) /3 = 24.
Or, p + r + t = 3 * 24 = 72. ........ (2)
Now, subtracting (2) from (1)
We have, (p + q + r + s + t) - ( p + r + t) = 140 - 72
Or, q + s = 68.
Thus, sum of q and s is 68.
