Answer:
125%
Step-by-step explanation:
First Method
Let the number of pencils bought :
LCM of 4, 6 = 12
=> C.P. of 6 pencils = Rs. 4
=> C.P. of 12 pencils = Rs. 8
=> S.P. of 4 pencils = Rs. 6
=> S.P. of 12 pencils = Rs. 18
Profit = Rs. (18-8) = Rs. 10
Profit % = 10/8 x 100 = 125 %
Second Method
Here, a = 6, x = 4, b = 4, y = 6
Gain % = (ay - bx / bx) x 100 %
=> (6 x 6 - 4 x 4 / 4 x 4) x 100 %
=> (36 - 16 / 16) x 100 %
=> 20/16 x 100 %
=> 125 %
