in the resultant mixture is

(b) 40 kg
(c) 42 kg
(d) 44 kg
ANSWERS WITH SOLUTION:
1.(b) 80 kg 800 Matlab sp 10₹/kg
100 kg 750 Matlab C.P 7.5₹/kg
Profit = (sp-cp)*100/cp =33 1/3
2.(d)
3.(a) Let x kg be the weight of the person.
=> 7 * 42 + x = 8 * (42 + 3)
=> 294 + x = 360
=> x = 360 – 294 = 66 kg
so The weight of the new person is 66 kg.
4.(a) The net gain to Kishan is only through interest by the end of the first year. His net gain
= 12, 000 [(12 ×1)/100- (8 ×1)/100] = 12, 000× 4/100 = Rs. 480.
5.(d) 5th.
3m = 4 days
1m = 12 days
So efficiency of 1m = 1/12
=> 5w = 5d
1w = 25d
Eff of w = 1/25
=> 8b = 10d
B = 80d
Eff of 1B = 1/80
=> Now
6(1/12) + 5(1/25) + 24(1/80)
= 1/2 + 1/5 + 3/10
= 10/10 = 1 day
1.(b) 80 kg 800 Matlab sp 10₹/kg
100 kg 750 Matlab C.P 7.5₹/kg
Profit = (sp-cp)*100/cp =33 1/3
2.(d)
3.(a) Let x kg be the weight of the person.
=> 7 * 42 + x = 8 * (42 + 3)
=> 294 + x = 360
=> x = 360 – 294 = 66 kg
so The weight of the new person is 66 kg.
4.(a) The net gain to Kishan is only through interest by the end of the first year. His net gain
= 12, 000 [(12 ×1)/100- (8 ×1)/100] = 12, 000× 4/100 = Rs. 480.
5.(d) 5th.
3m = 4 days
1m = 12 days
So efficiency of 1m = 1/12
=> 5w = 5d
1w = 25d
Eff of w = 1/25
=> 8b = 10d
B = 80d
Eff of 1B = 1/80
=> Now
6(1/12) + 5(1/25) + 24(1/80)
= 1/2 + 1/5 + 3/10
= 10/10 = 1 day
6.(d)
7.(b) 7th.
Let Karan has x rupees!
He distributed y rupees to A n B each!
Freind will get = 1/2 y
Karan left with = 1/3 y rupee
Now
Y/2 - y/3 = 60k
=> y = 3,60,000
Again
X = y + y + y/2 + y/3 = 17/6y
= 17*360000/6 = 102,000 or Q7.....see this question can be done without touching pen,,,,
see the options .,...a is 45 and b is 90....if original number is divisible by 5 then the unit place is either 0 or 5....
and after reversing the number 45 becomes 54 still divible by 9 and 90 becomes 09 divisble by 9......
so both A and B possible.
8.(a) Let the initial number of males be 3x and the initial number of females be 2x.
After three women joined and three men left, the ratio was 11 : 9.
=> (3x- 3)/(2x+3 )=11/9
=> 9(3x – 3) = 11 (2x + 3)
=> 27x – 27 = 22x + 33
=> x = 12
so Total number of people present in the hall initially
=> (3 + 2) 12 = (5)(12) = 60
9.(d)
10.(d) Quantity of sugar in first mixture = 3/5 * 40 kg = 24 kg
Quantity of sugar in second mixture = 2/3 * 30 = 20 kg
so Total quantity of sugar in the resultant mixture
= 24 kg + 20 kg = 44 kg.
