Question

Roja had some marbles. Ruhana gave her 18 more marbles. Now Roja has four times the number of marbles she had earlier. 
How many marbles did she have in the beginning?​

Answer 1

Answer:

She have 6 marbles in beginning

Step-by-step explanation:

Because if we add 18 in 6 we get 24

In equation, 6+18=24

Now,6*4=24

Therefore,She have 6 marbles in beginning.

Answer 2

Answer

No of marbles Roja had = x

x + 18 = x × 4

x × 4 = 4x

= 4x - 18

therefore, 18 is the third multiple of x.

therefore, the value of x is 6

(6+18=24) = (6×4=24)

Roja had 6 marbles in the beginning.
