Let the longer side = l, shorter side = b and diagonal = d
Then, area of rectangular carpet = l x b = 60 ....(1)
And from question d + l = 5b
? d = 5b - l ...(2)
? d2 = 25b2 + l2 - 10 x lb
? l2+ b2 = 25b2 + l2 - 10 x lb
? l2+b2 = 25b2 + l2 - 10 x 60
? 24b2 = 600
? b = ?25 = 5 m
? l = 60 / b = 60 / 5 = 12 m
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
