Question

Ram bought some apples, on the way to home he met with his three friends atul, bhima and chandan one by one and he gave each friend half of the apples and one extra apple, at the end ram had 7 apples left, how many apples did ram buy?

Answer 1

atul=x+1

bhima=x+1

chandan=x+1

left=7

total apples= x+1+x+1+x+1+7

=3x+3+7

=3x+10

Answer 2

Answer:

70

Step-by-step explanation:

Let x be the number of apples contained by Ram initially,

∵  He gave half of the apples and one extra apple to Atul, Bhima and Chandan one by one,

So, apples get by Atul = $\frac{x}{2}+1$

Remaining apples = $x-\frac{x}{2}-1$ = $\frac{x}{2}-1$

Apples get by Bhima = $\frac{x/2-1}{2}+1$

$=\frac{x-2}{4}+1$

$=\frac{x-2+4}{4}$

$=\frac{x+2}{4}$

Remaining apples = $\frac{x}{2}-1-\frac{x+2}{4}$

$=\frac{x}{4}-\frac{3}{2}$

Apples get by Chandan = $\frac{x/4-3/2}{2}+1=\frac{x-6}{8}+1$

$=\frac{x-6+8}{8}$

$=\frac{x+2}{8}$

Remaining apples = $\frac{x}{4}-\frac{3}{2}-\frac{x+2}{8}=\frac{x-6}{4}-\frac{x+2}{8}=\frac{2x-12-x-2}{8}=\frac{x-14}{8}$

According to the question,

$\frac{x-14}{8}=7$

$x-14=56$

$x=70$

Hence, Ram bought 70 apples.
