Answer
1. A
Let the investment made by Raghu be 100x, so Mohit’s investment = 90x and rahul’s investment =108x
108x+90x + 100x = 298x = 17880
X=60
So, Raghu investment = 100x = Rs.6000
2. B
Total commission in first month = Rs.3200
Total commission in second month = Rs.6400
Total commission in thired month = Rs. 9600
Total commission in fourth month = Rs.4800
“C’s share in the commission =” 4/16 of 3200+ 5/16 of 6400+ 3/16 of 9600+ 5/16 “of 4800”
=800 + 2000 + 1800 + 1500 = Rs.6100
“C’s average monthly earnings = ” “6100” /4 “= Rs.1525.”
3. C
Final selling price of jeans in shop A = (900- 900×0.15)- (900-900×0.15)×0.15 = Rs. 650.25
Final selling price of jeans in shop B = (900-900×0.20)- (900-900×0.20)×0.10= Rs.648
Difference = Rs.2.25
4. A
Sedimentation occurs when more than 20g of sugar is present in 100g of water.
Amount of sugar in 1kg of water = 70g
“Amount of water needed for sedimentation to start = ” “70x×100″ /20 ” = 350g”
Amount of water that should evaporate = 1000-350 = 650g
“Time required for eveporation =” ” 650″ /”32.5 ” “= 20 hours.”
5. B
Let the ratios in which they are mixed is x and y
Therefore A=4/5x+3/8y
B=1/5x+5/8y
Now A/B=2/3
On solving we get x:y=1:16
6. D
7. D
8. C
9. D
10. B
