M + T + W = 3 x 37 = 111° C .....(1)
T + W + Th = 3 x 34 = 102 ° C ......(ii)
Let M = y
Then, Th = 4y/5
subtraction (ii) from (i) we get,
M - Th = 9° C
? y - 4y / 5 = 9° C
? y = 45° C
? Temperature on thursday = (4 x 45) / 5° C
= 36° C
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
