Ramu cuts a metal plate into two equal halves. He again cuts one half into smaller pieces of equal size. Each small piece is of 20 grams in weight. If he has a total of 7 pieces of the metal, what was the weight of the original plate in grams ? Correct Answer 240

Given

Ramu cuts a metal plate into two equal halves

He again cuts one half into smaller pieces of equal size

Each small piece is 20 grams in weight

Calculation

After cutting the metal plate into two equal half now the plat is divided into two-part

⇒ Again divide one half into equal part

If he has a total of 7 part then that half part which was divided into equal half = 6

⇒ Weight of 6 part = 6 × 12 = 120

This is the weight of one half = 120 gm

⇒ Weight of another half = 120 gm

∴ The total weight is 240 gm
