(A) 1 years

(B) 2 years

(C) 3 years

(D) 4 years

Ans: B

Present age of 5 members = (5 × 17 + 3 × 5) years = 100 years.

Present age of 5 members and a baby = 17 × 6 = 102 years.

∴ Age of the baby = (102 - 100) years = 2 years.

(A) Rs. 16

(B) Rs. 18.95

(C) Rs. 20

(D) Rs. 25.71

Ans: C

Total earning for the week

= Rs. (4 × 18 + 4 × 22 - 20) = Rs. 140.

∴ Average earning = Rs. \$\${140}/{7}\$\$ = Rs. 20.

Question: 3

The average age of three members of a family was 24 five years ago. At present the average age of the family including a new member is 22. Find the age of the new member.

(A) 1 year

(B) 2 year

(C) 3 year

(D) 4 year

Ans: A

Total age of family members 5 years before = 24 x 3 = 72 years.

Total age of family members at present = (24 + 5) × 3 = 87 years

Total age of family member including a new members
at present = 22 × 4 = 88 years

∴ Age of new member = 88 - 87 = 1 year.

Total marks of 10 boys = 70 × 10 = 700%.

The mean marks of 15 girls = 60%

Total marks of 15 girls = 60 × 15 = 900%

∴ Sum of the total marks of 25 students = 700 + 900 = 1600%

∴ The mean marks of all the 25 students = \$\${1600} / {25}\$\$ = 64%.
