8. Daily requirement is 2600 calories.
Proteins:
12% of daily requirement:
12% of 2600 calories
12/100 ×2600
= 12 × 26
= 312 calories
Fats:
25% of the daily requirement
25% of 2600 calories
25/100 × 2600 = 25 × 26
= 650 calories
Carbohydrates:
63% of 2600 calories
63/100 × 2600
63 × 26
= 1638 calories
9. Given that, Total runs = 62 runs
Total number of balls = 96 balls
A cricketer hits 3 sixes, 8 fours, 2 twos and 8 singles
Therefore, to find the percentage, proceed the following
1) Sixes
A cricketer hits 3 sixes = 3(6) = 18
Therefore, percentage of sixes= 1862×100
= 29.03%
2) Fours
A cricketer hits 8 four = 8(4) = 32
Therefore, percentage of fours= 3262×100
= 51.61%
3) Twos
A cricketer hits 2 twos = 2(2) = 4
Therefore, percentage of twos= 462×100
= 6.45%
4) Singles
A cricketer hits 8 singles = 8(1) = 8
Therefore, percentage of singles= 862×100 = 12.90
10. Assume that the cricketer scored “a” runs in 6’s.
20% of 120 = a
a = 24
Therefore, the cricketer scored 24 runs by hitting 6’s
Assume that the cricketer scored “b” runs in 4’s.
30% of 120 = b
b = 36
Therefore, the cricketer scored 36 runs by hitting 4’s
Assume that the cricketer scored “c” runs in 2’s
25% of 120 = c
c = 30
Therefore, the cricketer scored 30 runs by hitting 2’s
Assume that the cricketer scored “d” runs in 1’s.
24+36+30+d = 120
d = 30
Therefore, the cricketer scored 30 runs by hitting 1’s
11. Let the investment of Radha be Rs. 'a'
From the given information, we can write it as
22% of a = 187
= 22100×a=187
a = 187×10022
a= 850
Therefore, the investment of Radha is Rs. 850
12. Let the total income of Rohit for a year, 1997 be Rs. 'a'
From the given information, we can write it as
12% of x = 1440
=> 12/100 × a = 1440
a = 1440 × 100/12
a = 12000
Therefore, the total income of Rohit during 1997 is Rs.12,000.00
