a rectangle having length 120 cm and width 50 cm . if the length of the rectangle is increased by ten percent then how much percent the breadth should be decreased so as to maintain the same area .
"explanation : solution : ( 10 / ( 120 + 10 ) * 100 ) % = 7.69 % answer : d"
multiply(add(const_1, divide(divide(multiply(120, 50), add(120, divide(multiply(multiply(const_3, const_10), 120), const_100))), 50)), const_10)
