to fill a tank , 25 buckets of water is required . how many buckets of water will be required to fill the same tank if the capacity of the bucket is reduced to 1 / 5 of its present ?
"let capacity of 1 bucket = x capacity of the tank = 25 x new capacity of the bucket = 1 x / 5 hence , number of buckets needed = 25 x / ( 1 x / 5 ) = ( 25 × 5 ) / 1 = 125 answer is e ."
divide(multiply(25, add(const_4, const_1)), const_2)
