109 * 34 – 108 * 33
= 3706 – 3564 = 142

Let the total number of children be x.
Then x × 20/100 × x = 605
=> x2 = 3025
=> x = √3025 = 55
Number of sweets received by each child
= (20/100 ×55) = 11
A. 70%
B. 60%
C. 40%
D. 30%
Explanation:
Total number of employees be 100
Then number of men = 6000/100 = 60
Number of women = 4000/100 = 40
Therefore, number of men drawing more than Rs. 50000 = 2400/100 = 24 men
Since the number of total employees drawing more than Rs. 50000 = 3600/100 = 36
Number of women who draw more than Rs. 50000 = 36- 24 = 12
Number of women who draw less than Rs. 50000 = 40 -12 = 28
Therefore, Percentage of the women who draw less than Rs. 50000 per year = 28/40 x 100% = 70%
A. 21
B. 22
C. 23
D. 24
Let the initial number of members in the group be n.
Initial total weight of all the members in the group = n(48)
From the data,
48n + 78 + 93 = 51(n + 2) => 51n – 48n = 69 => n = 23
Therefore there were 23 members in the group initially.
A. Rs. 12
B. Rs. 12.96
C. Rs. 14.40
D. None of these
Explanation:
90 : 10.80 :: 120 : x
X = (10.80 ×120)/90 = 14.40
Hence, the toy must be sold for Rs. 14.40
