Let original rate of rice be ? x per kg
Reduced rate = ? [(100 - 6.25) x (1/100) x W]
= ? 15W/16 per kg
According to the question
120/(15W/16) - 120/W = 1
? (120 x 16)/15W - 120/W = 1
? 120 x 16 - 1800 = 15W
? 128 - 120 = W
? W = ? 8 per kg.
? Reduced rate = ? (15/16) x 8 per kg
=? 7.50 per kg
4th observation i.e., 8 is the median.
47/10000 = .0047
.02 =(2/100) x 100% =2%
Let N / 11 = 233
Then, N = 233 x 11 = 2563
? Missing digit is 5.
121012 = 12 x 10084 + 4
? remainder = 4
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
