Question

the weight of 1 coin is 11 grams then how many coins will weigh 1.76 kg

Answer 1

Hey



We will solve it by # Unitary method



Solution :-


11 gram = 1 coin


1 gram = 1 / 11 coin


1.76 * 1000 gm = 1.76 * 1000 / 11 coin


= 176 * 1000 / 11 * 10


= 16 * 100


= 1600


So , number of coins = 1600



[ NoTe :- 1.76 kg = 1.76 * 1000 grams ]



thanks :)

Answer 2

Hey!

Unitary method.

1.76 kg= 1.76*1000=1760gram.

11 gram is the weight of 1 coin.
1 gram is the weight of 1/11 coins.
So 1760 gram is the weight of 1/11 *1760 coins
= 160coins.

Hope it helps.
