Correct Answer: 48 Paise
Explanation:
Let the Required cost be X paise. Less Weight , Less cost (Direct Proportion)
Therefore, 250 : 200 :: 60 : x
=> (250 * x) = (200 * 60)
=> x= 48
Correct Answer: Rs. (yd/x)
Explanation:
Cost of x metres = Rs. d.
Cost of 1 metre = Rs.(d/x)
Cost of y metres = Rs.[(d/x).y] = Rs.(yd/x)
Correct Answer: 42
Explanation:
After 10 days : 150 men had food for 35 days.
Suppose 125 men had food for x days.
Now, Less men, More days (Indirect Proportion)
125 : 150 :: 35 : x 125 x x = 150 x 35
Correct Answer: 450
Explanation:
Let the required no of hectares be x. Then
More men, More hectares (Direct proportion)
More days, More hectares (Direct proportion)
=> ( 8 * 24 * x) = (36 * 30 * 80)
=> x= 450
Correct Answer: Rs. 340
Explanation:
Assume first child (the youngest) get = Rs. x
According to the question ;
each son having Rs. 30 more than the younger one
Second child will get = Rs. x + 30
Third child will get = Rs. x + 30 + 30 = x + 60
Forth child will get = Rs. x + 30 + 30 + 30 = x + 90
Fifth child will get = Rs. x + 30 + 30 + 30 + 30 = x + 120
Total amount they got = Rs. 2000
x + (x+30) + (x+60) + (x+90) + (x+120) = 2000
5x + 300 = 2000
5x = 1700
x = Rs. 340
So the youngest child will get Rs. 340.
Correct Answer: 16

=> x =
=> x = 16.

=> 15 * 12 * x = 10 * 18 * 6
=>x = 6
Correct Answer: 32
Explanation:
(Men 14 : 16) : (Hrs/Day 12 : 7) :: 48 : x
14 * 12 * x = 16 * 7 * 48 or x = 32
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
