View Answer Discuss Work SpaceAnswer: option c
Explanation:
The fruit content in both the fresh fruit and dry fruit is the same.
Given, fresh fruit has 68% water. So, remaining 32% is fruit content. weight of fresh fruits is 100kg
Dry fruit has 20% water.so remaining 80% is fruit content.let weight of dry fruit be y kg.
Fruit % in fresh fruit = Fruit % in dry fruit
Therefore, (32/100) x 100 = (80/100 ) x y
we get, y = 40 kg

A. 11
B. 10
C. 9
D. 8
View Answer Discuss Work SpaceAnswer: option d
Explanation:
Let the total number of children be x.
Then, x * (20% of x) = 320
=> x * 20x/100 = 320
=> x^2 = 320*5
=> x=40
Number of candies received by each child = 20% of 40 = 8
| 23. | A salesman gets commission on total sales at 9%. If the sale is exceeded Rs.10,000 he gets an additional commission as bonus of 3% on the excess of sales over Rs.10,000. If he gets total commission of Rs.1380, then the bonus he received is: |
|---|
A. Rs.180
B. Rs.120
C. Rs.480
D. data insufficient
View Answer Discuss Work SpaceAnswer: option b
Explanation:
Let the Total sales = 100x
Commission @ 9% = 9x
Commission beyond 9% @ 3% (as Bonus) = (100x - 10000)*(3/100) = 3x - 300
Total commission = 9x + (3x - 300) = 12x - 300
Given, 12x - 300 = 1380
x = 1680/12 = 140
Therefore, Bonus = 3x - 300 = 420 - 300 = 120
| 24. | Of the 10000 citizens of a town, 60% are males of whom 20% are literate. If, of all the citizens, 25% are literate, then what percent of the females of the town are literate ? |
|---|
A. 32.5 %
B. 43 %
C. 46.6 %
D. 53.2 %
View Answer Discuss Work SpaceAnswer: option a
Explanation:
Number of males = 60% of 10000
= 6000
Number of females = (10000 - 6000) = 4000
Number of literates = 25% of 10000 = 2500
Number of literate males = 20% of 6000 = 1200
Number of literate females = (2500 - 1200) = 1300
Required pecentage = (1300/4000 * 100 ) = 32.5 %
Note: The question can also be solved by assuming total citizens as 100 as only percentage is required.
