​

Answer 1

1. mean = sum of the numbers /number of the numbers

36+35+50+40+60+55/6

=46

So 46 is the mean.

2.i.7×3/5=21/5

ii.20×4/5=16

iii.2/3×4=8/3

4. Ramesh solved 7/7 of an exercise.

Seema solved 4/5.

7/7 or 4/5

Lcm of 7 and 5 =35

7/7=7×5/7×5=35/35

4/5=4×7/5×7=28/35

35/35 is greater than 28/35.

So, seema solve lesser.

6. Marks are 85,76,90,85,40,56,93,81,75

i.Lowest is 40.

Highest is 93.

ii. Range of Marks =93-40=53

iii. mean = sum of the number / number of the number

85+76+90+85+40+56+93+81+75/9

=75.66

Hope it is helpful.
