child A ate 3/5 of 1000g of chocolate which is 600g
Child B ate 300 gms hence twice that would be 600g

A= (3/5)*1000=600
B=2*300 =600
hence answer C

instead of (3/5)*1000=600
my friend what you can do is just multiply 2 on both numerator and denominator so its becomes easier to estimate the percentage hence easy to determine the weight.
it would be 6/10 which is 60% so 600 grams.
just make denominator either 10, 100 or as close to 100 as possible so you can take an approximation
