fem and CA Bem
Step-by-step explanation:
Q.5. 12% of 60
=12/100×60
=36/5
=7⅕
Q.6. Gain = S.P.–C.P.
Gain = 110–80
Gain = Rs.30
So, gain% = gain/C.P.×100
= 30/80×100
= 150/4
= 37 whole (2 by 4)%
Q.7. Area = 96cm²
Breadth = 8cm
Length = x
l×b = Area of a rectangle
x×8 = 96cm²
8x = 96cm²
x = 96/8
x = 12cm
Thus, the length is 12cm.
Q.7. Diameter = 14cm
So, radius = 14/2 = 7cm

So, circumference = 2×22/7×7
= 44cm
