प्रश्न

A student used the proportion `n/100 = 5/32` to find 5% of 32. What did the student do wrong?

बेरीज

उत्तर

Given, student used the proportion `n/100 = 5/32`

⇒ 5% of 32 will be calculated as `5/100 xx 32`

Since, x% of `n = x/100 xx n`

= `32/20`

= 1.6

But student finding percent is 5 of 32.
