Question

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

Answer 1

Ramu cuts a plate ½ and again he cuts another half from the half and brokes it into 7pcs each 20gm
7×20=140
adding the half of the half
2×140=280
1/2 plate
2×280=560

Answer 2

Answer:

Given that total number of pieces are 7

6small pieces+half piece=7

small piece weight is 20 grams

so, 6*20=120 grams

6 small pieces equal to one half piece,

6small pieces+half piece=7,

6*20+120=240 grams.
