11060809040Option C
448 ÷ 28 × 5
= 16 × 5 = 80 - 459% of 849.947 + 266.5% of 6284.012 – 1486.002 = ?
1852011130123401556019140Option E
(460×850)/ 100 + 2.665 × 6284 − 1486
= 3910 − 1486 + 2.66 × 6284
== 19140 - (9321 + 5406 + 1001) ÷ (498 + 929 + 660) = ?
6.37.55.58.26.5Option B
(9321 + 5406 + 1001) ÷ (498 + 929 + 660)
= 15728 ÷ 2087 == 7.5 - 5237.897 – 6629.010 + 7153.999 – 2205.102 = ?
42053869458035583560Option D
5238 − 6630 + 7154 − 2205
= 12392 − 8835 = 3557 == 3558 - 1679 ÷ 14.95 × 5.02 = ?
522560458555652Option B
1680 ÷ 15 × 5
= 112 × 5 = 560 - In a mixture of Zinc, Copper and tin, Zinc is 40% in the mixture and copper is 25% in mixture, 20kg of mixture taken out and 12kg zinc and 15kg copper added in mixture so that new ratio between zinc and copper becomes 6 : 5. Find the initial quantity of mixture ?
90 kg80 kg60 kg50 kg20 kgOption B
Ratio between zinc : copper : tin in mixture
= 40 : 25 : 35
= 8 : 5 : 7
Let initial quantity of zinc, copper and tin in mixture 8x, 5x and 7x respectively.
[8x – 20*8/20 + 12]/[5x – 20*5/20 + 15] = 6/5
=> x = 4
Initial quantity
= 8 * 4 + 5 * 4 + 7 * 4
= 80 kg - Mohit and Ankit entered into partnership business, Mohit invested Rs. 10200 and Ankit invested Rs. 10800 for first six months after that Mohit double his capital for next 4 months then withdraw its investment and Ankit half his initial amount for next six months. If they got total profit of Rs. 50000 after a year then find the profit share of Mohit?
Rs. 29750Rs. 28760Rs. 27050Rs. 22760Rs. 31750Option A
Ratio of profit of share of Mohit and Ankit
= (10200 * 6 + 20400 * 4) : (10800 * 6 + 5400 * 6)
= 119 : 81
Mohit’s share
= 50000* 119/200 = Rs. 29750 - Veer invested Rs.40000 at the rate of 20% compound interest. If first year interest calculated half yearly and second year calculate annually, then find the total interest Veer gets after 2 year ?
Rs. 19500Rs. 18000Rs. 15050Rs. 11000Rs. 18080Option E
Half-yearly rate = 20/2 = 10%
Overall rate = 10 + 10 + 10*10/100 = 21%
1st year interest = 40000*21/100 = Rs. 8400
2nd year interest = (40000 + 8400)*20/100
= Rs. 9680
Total interest = Rs. 18080 - In 160 litre mixture of milk and water, ratio of milk to water is 5 : 3, if 24 ℓ mixture taken out from the mixture and same amount of water added in mixture then find the percentage of water in new mixture found ?
46(7/8)%26(5/8)%32(3/4)%41(5/8)%40(6/8)%Option A
Mixture = 160 l Milk : Water = 5:3
Quantity of Milk = 160*5/8 = 100 l
Quantity of Water =160*3/8 = 60 l
24 l mixture is taken out
Milk = 24 * 5/8 = 15 l
Water = 24 * 3/8 = 9 l
New quantity : Milk = 100 – 15 = 85 l
Water = 60 – 9 + 24 = 75 l
% of water in the new mixture
= 75 / (85+75)*100 = 46(7/8)% - Still water speed of boat is three times of the current speed. If a boat travel 72 downstream and return upstream in total 33 hours in which boat lost 25% of its upstream speed while returning, then find speed of boat in still water ?
6 km/hr4 km/hr8 km/hr2 km/hr3 km/hrOption D
Let still water speed of boat is x km/hr and current speed is y km/hr
Given x = 3y
Now, 72/(3y+y) + 72/(3y-y)*3/4 = 33
=> 72/4y + 72/3y = 33
=> y = 2 km/hr.
