Answers :
Directions (1-5):
1) Answer: D
(60/100) × 360 + (30/100) × 240 – (25/100) × 400 =?
216 + 72 – 100 =?
? = 188
2) Answer: C
4342.1 + 641.7 + 73.2 + 7.2 =? – 35.9
?= 5100.1
3) Answer: A
85/100 * x * 4700 = 3196
x = (3196 * 100)/(85 * 4700)
x = 4/5
4) Answer: C
(240/100 * 775)/x = 60
x = 31
5) Answer: B
142 × 7 of 30% of 840 ÷ 21 = x × 784
196 × 7 × 30/100 × 840/21 = x × 784
x = 21
Directions (6-10):
6) Answer : E
(40 * 12.5) + (25 * 15.10) = (65 * x)
= > 500 + 377.5 = (65 * x)
= > x = Rs.13.5
20 % profit =13.5×120 / 100
SP of the mixture = Rs.16.20
7) Answer: C
Required number of ways = ELECTION = 8!/2! = 20160
8) Answer: D
Probability = (32C1 * 8C1)/40C2
= (32 * 8)/(40 * 39/1 * 2)
= (32 * 8 * 2)/(40 * 39)
= 64/195
9) Answer: A
Let three numbers 2x, 5x and 7x.
LCM = 70x
Given 70x = 3500
x = 50
The numbers are 100, 250 and 350
HCF = 50
