The correct option is a (57)

For Ist circle problem,

= 3+3+4+5

= 15 x 2 (we multiple it by 2)

= 30

Now we multiple by (2) x 2 and subtract by -5 we get

= 30 - (2)2 - 5

= 30 - 9

= 21

Now we multiply by 3 we get

= 21 x 3

= 63 (given)

For 2nd circle problem,

= 8 + 4 +4 +3

= 19 x 2 (we multiple it by 2)

= 38

Now we multiple by (4) x 4 and subtract by -5 we get

= 38 - (4)4 - 5

= 38 - 21

= 17

Now we multiply by 3 we get

= 17 x 3

= 51 ( given)

For 3rd circle problem ,

= 9 + 7 + 5 +9

= 30 x 2 (we multiple it by 2)

= 60

Now we multiple by (6) x 6 and subtract by -5 we get

= 60 - (6)6 -5

= 60 -41

= 19

Now we multiply by 3 we get

= 19 x 3

= 57
