Answer keys:
1) Answer: C)
Let Suhas' salary =Rs. x
According to question,
x×15/100×11/15 = 1650
x = Rs.15,000/-
2) Answer: D)
According to question,
B : C =1 :3
Ratio of work done by A, B and C in one day
C's 1 day's work =3 unit
C's 16 day's work =3 x 16 = 48 unit
Time taken by A, B and C to complete the
Work = 48/4+1+3 = 48/8
3) Answer : D)
Let the average age of remaining 20 girls = x years According to question, 20x12+20x16+20xx=900
240 +320 +20x = 900
20x =900-560
x =17 years
4) Answer: C)
Let B invested the money for x months. According to question,
Ratio of investment of A and B = Ratio of their profit
5*7 / 7*x = 1/2
X = 10 months
5) Answer: B)
Let the cost price of article = Rs. x
According to question,
x * 92/100 =1380
x = Rs.1,500/-
Required price = 1500 * 108/100
6) Answer: C)
Let the marked price of goods = Rs.100/-
Selling price of goods = 100 x80/100 = Rs.80/-
Cost price of goods = 80 x 100/125= Rs.64/-
When a discount of 10% is allowed on the
marked price of goods then selling price will be
=100 x 90 = Rs.90/-
Required profit percentage
90-64/64 * 100 = 26/64 * 100
= 325/8 = 40 5/8%
7) Answer: A)
8) Answer: A)
1 minute work of tap A = 1/60
1 minute work of tap B = 1/30
(A + B)'s 1 minute work = 1/60+ 1/30 = 1+2/60 = 3/60
.•. Time taken by (A + B) to empty the tank =20 min.
9) Answer: B)
New rate of sugar = rupees * Percentage / Quantity
270/1 * 10/100 = x
=Rs.27/- per kg
Let the original price of sugar = Rs.x
According to question,
x *90/100 =27
x=27x100/90
x = Rs.30 per kg
10) Answer: D)
Let the length of the train = x metre According to question,
50+ x /14 = x/10
500 + 10x = 14x
We know that
Speed = Distance/time
125+50/14 =175 / 14 m/s
Speed of the train 175/14 * 18/ 5 = 45 km
