Question

(a)100%
(b) 119,7%
(c) 90%
(d) None of these

Answer 1

Answer:

Step-by-step explanation:

Let original side be x

Volume=x³=100x³/100

Side after 30% increase=x+3x/10=13x/10

Volume=169x³/100

Increase=(169x³/100) -(100x³/100) =69x³/100

Increase percentage=(69x³/100)/(100x³/100) =69%

Answer=(d) None of these
