Q.1) Answer: b

Required average = ((40*25) + (30*20))/70=1600/70=23 years

Q.2) Answer: c

Let us take five consecutive odd numbers x, x+2, x+4, x+6, x+8 and seven consecutive numbers y, y+1, y+2, y+3, y+4, y+5, y+6

Average of seven consecutive number = y+3=30=>y=27

Sum of the five consecutive odd numbers = 27+25+23+21+19=115

Q.3) Answer: d

Sum of the age of Father, mother and Daughter = 26*3=78 yrs

Sum of the ages of Father and daughter = 21*2+10=52 years

Age of mother= 78-52 =26

Mother’s age after 10 yrs = 26+10=36 years

Q.4) Answer: a

Let us take five consecutive even numbers x, x+2, x+4, x+6, x+8 and six consecutive odd numbers y, y+2, y+4, y+6, y+8, y+10





=>x+y=73 — (2)

Simplify the above equation (1) and (2), we get x=42

Required difference = (482-332)=1215

Q.5) Answer: c


((9*40)-(4*30))/5=240/5=48 kg

Sub the equation (2) in (1),


A= 40


D= 76-52= 24

Q.9) Answer: d

Sum of A, B and C = 90 yrs —- (1)

Sum of A, C and D = 90 yrs —- (2)

C= D+10

A= C-20 (or) D-10

Simplify the equation (1) and (2), we get B=D

Substitute all the values in equation (1) we get A= 20 years

D= 20+10=30 years, C =20+20=40 yrs

Required average = (20+30+40+30)/4=120/4=30 years
