- Total of the age of husband and wife = 2 × 26 = 52
Total of the age of husband and wife after 6 years + age of the 2 year old child
+ age of the 2 year old child
= 52 + 6 + 6 + 2 = 66
∴ Average of the family = 663 = 22
- Runs scored in the first 12 over’s = 12 ×4 = 48
Total runs = 238
Remaining runs to be scored = 238 – 48 = 190
Remaining over’s = 38
∴ Required run rate = 19038 = 5
- Total weight of 20 student = 20 × 44 = 880
Total weight of 10 student = 10 × 38 = 380
Total no of student = 880+38030 = 126030 = 42kg
- Since the month begins with a Sunday, so there will be 5 Sunday in the month.
Total visitors on Sunday = 440 × 5 = 2200
Total visitors on other days = 260 × 25 = 6500
∴ Required average = 2200+650030 = 870030 = 290
- Required average = 30×65+35 ×70+40 ×7565 +70 75 = 7400210
= 35.24
- Total present age of husband, wife and child = 25 × 3 + 5 × 3 = 90
Total present go of wife & child = (18 × 2 + 4 × 2) = 44
∴ present ago of husband = 90 – 44 = 46 years
- The average marks are = 60+65+70+72+78 5 = 3455 69
- Weight of teacher = 42 × 21 – 40 × 20 kg
= 882 – 880 = 82 kg
- Total weight increased = 6 × 2 = 12 kg
Weight of new person = 55 + 12 = 67 kg
- Present age of A & B = 25 × 2 + 5 × 2 = 60
Present age of A, B & C = 28 × 3 = 84
∴ Ago of C = 84 – 60 year = 24 year
