radius of each identical circle be =r
radius of big circle =3r
quant A: circumference of big circle (with center O)=2π(3r)=6πr
quant B: sum of circumference of 3 small circles = 3*(2πr)=6πr (here 2πr is circumference of each small circle)
so quant A = quant B
option C is correct
radius of big circle =3r
quant A: circumference of big circle (with center O)=2π(3r)=6πr
quant B: sum of circumference of 3 small circles = 3*(2πr)=6πr (here 2πr is circumference of each small circle)
