Correct Answer: Rs.220
Explanation:
Let the required Price be Rs. X .Then, Lest toys , Less cost (Direct Proportion)
Therefore 6 : 5 :: 264.37 : x
=> 6 * x = 5 * 264.37
=> X= 220.308
Therefore, Approximate price of 5 toys = Rs. 220
Correct Answer: 32
Explanation:
(Men 14 : 16) : (Hrs/Day 12 : 7) :: 48 : x
14 * 12 * x = 16 * 7 * 48 or x = 32
Correct Answer: 6 hours a day
Explanation:
More Men, Less Hours {Indirect Proportion}
Less Days, More Hours {Indirect Proportion}
=> 15 * 12 * x = 10 * 18 * 6
=>x = 6

Let the required number of bottles be x.
More weavers, More mats (Direct Proportion)
More days, More mats (Direct Proportion)
4 x 4 x x = 8 x 8 x 4
=> x =
=> x = 16.
Correct Answer: 195 seconds
Explanation:
Let the time required by x seconds.
Then, More cloth means More time (Direct Proportion)
So, 0.128 : 1 :: 25 : x
=> x = 195.31
So time will be approx 195 seconds
Correct Answer: 144
Explanation:
Less toys, Less Price (Direct Proportion)
So, let the price be Rs. x

23:12::276:x => x=(276*12)/23
=> x=144
So price of 12 toys will be Rs. 144

=Rs. [8000 * (23/20) * (23/20) * (21/20)]
= Rs. 11109. .
:. C.I. = Rs. (11109 - 8000) = Rs. 3109.
Correct Answer: 20000
Explanation:
Let sum=Rs.x
C.I. when compounded half yearly =
C.I. when compounded annually =
=> x=20000
