Question

Sarita has some marbles.Ameena has 10 more.Appu says that he has 3 more marbles than the number of marbles Sarita and ameena together have. Find the number of marbles appu has

Answer 1

let the sarita marble be x

ammena marble=x+10

Appu marble=x+10+3

Answer 2

Since it is not given how many marbles Sarita has, we shall take it to be x. Ameena then has 10 more, i.e., x + 10. Appu says that he has 3 more marbles than what Sarita and Ameena have together. So we take the sum of the numbers of Sarita’smarbles and Ameena’s marbles, and to this sum add 3, that is, we take the sum of x, x + 10 and 3.

I hope this will help you dear..
