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 7 / 10 of its present ?
"let capacity of 1 bucket = x capacity of the tank = 25 x new capacity of the bucket = 7 x / 10 hence , number of buckets needed = 25 x / ( 7 x / 10 ) = ( 25 × 10 ) / 7 = 35.71429 answer is d ."
divide(multiply(25, add(const_4, const_1)), const_2)
