Answers :
Direction (1-5) :
1) Answer: c)
[(32/100)*7500] ÷ x = (24/100)*2500X = 4
2) Answer: a)
(4/21)*10605 + (4/13) *7150 = 4x
2020 + 2200 = 4x
4220 = 4x
X = 4220/4 = 1055
3) Answer: d)
[(1/29) × 4350] + (5/13) × 2470 = 5x150 + 950 = 5x
5x = 1100
X = 1100/5 = 220
4) Answer: a)
3 1/7 + 7 5/14 – 8 3/7+ 2 9/14 + 3 ½ = x
X = (3 + 7 – 8 + 2 + 3) (1/7 + 5/14 – 3/7 + 9/14 + ½)
X = 7[(2 + 5 – 6 + 9 +7)/14]
X = 7(17/14) = 8(3/14)
5) Answer: b)
(5/11) * (7/9) * 2475 – x + (4572/4) = 463
875 – x + 1143 = 463
875 + 1143 – 463 = x
X = 1555
Directions (6 – 10):
Number of boys = 3/8 * 400 = 150 and number of girls = 250
Boys who speak only Hindi = 0.12 * 150 = 18
Girls who speak only English = 0.22 * 250 = 55
Students who speak only Hindi = 0.24 * 400 = 96
Hence Girls who speak only Hindi = 96 – 18 = 78
Hence Girls who speak both languages = 250 – 55 – 78 = 117
Boys who speak both languages = 18*6 = 108
Hence Boys who speak only English = 150 – 18 – 108 = 24
6) Answer: b)
No. of boys who speak Hindi = 18 + 108 = 126
7) Answer: d)
78 girls speak only Hindi
8) Answer: a)
No. of students speaking English = 400-18 -78 = 304
9) Answer: e)
Required % = 78/96 * 100 = 81.25 %
10) Answer: c)
Required ratio = 108: 117 = 12: 13
