Question

If the mean of p, q, r, s and t is 10, calculate the mean of p+1,q+2, r+3,s+4 and t+5​

Answer 1

13

Explanation:

The mean of a set of quantities is their sum divided by the number of them.

Mean

((p+1) +(q+2) +(r+3) +(s+4) +(t+5))/5

= (p +q +r +s +t)/5 +(1 +2 +3 +4 +5)/5

= mean(p, q, r, s, t) +15/5

= 10 +3 = 13

The mean of p+1,q+2, r+3,s+4 and t+5​ is 13.
