Answer: Rs.210
HOW?
36 Packets = 12 pencils
Total Pencils = 36 x 12 = 432 pencils
432 pencils = Rs.756
_____________________________________
12 Packets = 10 pencils
Total Pencils = 12 x 10 = 120 pencils
120 pencils = Rs. (unknown) or "z" as (variable)
_____________________________________
Main Equation = 432 : 756 :: 120 : z
Extremes = 432 x Z = 432z
Means = 756 x 120 = 90720
Linear Equation :
432z = 90720
Z = 90720 ÷ 432 = 210
