| D | 1305 | 1170 |
J : denotes the average number of males in villages A, B and C.
K: denotes the average number of females in villages B, C and D.
What is the average of J and K?
Answer & explanation
Correct answer: option 1
J : denotes the average number of males in villages A, B and C.
= \(\frac{1500 + 1460 + 1105}{3}\)
= \(\frac{4065}{3}\)
= 1355
K: denotes the average number of females in villages B, C and D
= \(\frac{1320 + 1180 + 1170}{3}\)
= \(\frac{3670}{3}\)
= 1223.33
Average of J & K = \(\frac{1355 + 1223.33}{2}\)
= 1289.17
