Question

Mina had 8 marbles. Tina had twice as many marbles as Zuha. when all of them put together their marbles, there were 29. find the number of marbles zuha and Tina had. solution

Answer 1

here we have ,
mina had 8 marbles
let Tina had = x no of marbles
therefore, zuha has 2x marbles
according to given data
8 + x +2x = 29
3x = 21
x = 7
therefore Tina had 7 marbles and zuha had 2*7 = 14 no of marbles

Answer 2

Mina has... 8 marbles
Let Zuha have.... X marbles
Let Tina have...... 2x marbles (as she has it twice)
8+x +2x=29
8+3x=29
3x=29-8
3x=21
X=21/3
X=7

Zuha has x which is 7 marbles


Tina has 2x which is 14 marbles
