Question

If the weight of the 12 sheets of thick paper is 40 grams how many sheets of the same paper would weight 16 2/3kilograms

Answer 1

let the no. of sheets be x, then;
12/40= x/162÷3
6/20 = 3x/162
x = 162×2/20
x= 16.2

Answer 2

If 40g = weight of 12 sheets
Thus, 1g = weight of 12/40 sheets.
Thus,
16 2/3kg = 50kg/3
= 50000g/3
= weight of (50000/3) × (12/40) sheets
=weight of(50000×12)sheets/ (3×40)
=weight of 6,00,000/120
=weight of 5,000 sheets.
