प्रश्न

Iniyan bought 5 dozen eggs. Out of that 5 dozen eggs, 10 eggs are rotten. Express the number of good eggs as percentage

योग

उत्तर

1 dozen eggs = 12

5 dozen = 5 × 12

Total eggs = 60 eggs

Rotten eggs = 10

Good eggs = 60 – 10 = 50

Fraction of good eggs = `50/60`

Percentage of good eggs = `50/60 xx 100/100`

= `50/60 xx 100%`

= `5/6 xx 100%`

= 83.33%

Percentage of good eggs = 83.33%
