Question

a toy is having a battery charging with 80% and for every one hour the battery is reduced by 5% then after 3 hours how much is the charging?

Answer 1

Answer:

65%

Step-by-step explanation:

Every one hour, 5% battery is reduced. So, if the current charging is 80%, and we have to find the charge of the toy after 3 hours, we will have to subtract 5 three times from 80. So, according to that:-

80-5-5-5=65

Hence, the answer is 65%!!!
