X * (96/100) = 23040
X = 240 * 100
X = 24000
A. 50
B. 72
C. 75
D. 76
Explanation:
Let the number of boys be 3x and number of girls be 2x.
Number of scholarship holders
= (20/100 ×3x+ 30/100 ×2x) = 6x/5
Number of those who do not hold scholarship
= (5x- 6x/5) = 19x/5
Required percentage = (19x/5 × 1/5x ×100) % = 76 %
A. 15 days
B. 20 days
C. 25 days
D. 30 days
(A + B)’s 1 day’s work = 1/10; C’s 1 day’s work = 1/50 (A + B + C)’s 1 day’s work = 1/10 + 1/50 = 6/50 = 3/25 Also, A’s 1 day’s work = (B + C)’s 1 day’s work
From (i) and (ii), we get : 2 x (A’s 1 day’s work) = 3/25 As 1 day’s work = 3/50 B’s 1 day’s work = 1/10 – 3/50 = 2/50 = 1/25 So, B alone could do the work in 25 days.

Explanation:
(180/37 of 14.8) / (17/60.1 of 180.30) = 72/51 = 24/17 = 1.41
A. 0.0256
B. 0.00256
C. 0.000256
D. 0.0000256
Explanation:
4 * 0.4 * 0.04 * 0.004 => 4 * (4/10) * (4/100) * (4/1000) = (256/1000000) = 0.000256
