Sum of the weights of the students after replacement

= [(52 × 45) – (48 × 5) + (54 × 5)] kg = 2370 kg.

∴ New average = \$\$({2370}/{45})\$\$ kg = \$\$52{2}/{3}\$\$kg.

Question: 4

The captain of a cricket team of 11 members is 26 years old and the wicket keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team?

(A) 23 years

(B) 24 years

(C) 25 years

(D) 27 years

Ans: A

Let the average age of the whole team be x years.

∴ 11x - (26 + 29) = 9 (x - 1)

⇔ 11 x - 9x = 46

⇔ 2x = 46

⇔ x = 23.

So, the average age of the team is 23 years.

Question: 5

Among five people with monthly income in Rs.15000, Rs.26000, Rs.16000, Rs.19000 and Rs.50000, how many will have income less than the mean income of five people?

(A) 1

(B) 2

(C) 3

(D) 4

Ans: C

Mean income = Rs. \$\$({15000 + 26000 + 16000 + 19000 + 50000} / {5})\$\$

= Rs. \$\$({126000} / {5})\$\$ = Rs. 25200.

Clearly, three people have monthly incomes below the mean income.
