Question

A box contains 160 marble ,out of which 10 marble got lost. What percentage of marble remain in the box​

Answer 1

Answer:

93.75%

Step-by-step explanation:

percentage = $\frac{remaining marbles}{total number of marbles }$×100

= 160-10/160   ×100

= 150/160 ×100

=15/16 ×100

= 1500/16

= 93.75%

Answer 2

Answer:

Let us assume that there are 100 marbles in the box.

If 20% of them are red then,

No. of red marbles = 20% of 100

= 20÷100 × 100

= 20.

The remaining number of marbles

= 100 - 20

= 80.

No. of green marbles = 25% of 80.

=25÷100 × 80

=20.

So, the percent of green marbles = 20%
