in a two digit number it is known that its unit ' s digit exceeds its 10 ' s digit by 4 and that the product of the given number and the sum of its digits is equal to 208 , what is the number ?
xy is 2 digit no . y - x = 4 ; ( 10 x + y ) * ( 2 x + 4 ) = 208 ; sub y = x + 4 ; we get 26 answer : c
add(add(divide(subtract(sqrt(add(power(add(multiply(add(const_10, const_1), 4), multiply(4, const_2)), const_2), multiply(multiply(4, multiply(add(const_10, const_1), const_2)), subtract(208, multiply(const_4, const_4))))), add(multiply(add(const_10, const_1), 4), multiply(4, const_2))), multiply(add(const_10, const_1), 4)), 4), multiply(divide(subtract(sqrt(add(power(add(multiply(add(const_10, const_1), 4), multiply(4, const_2)), const_2), multiply(multiply(4, multiply(add(const_10, const_1), const_2)), subtract(208, multiply(const_4, const_4))))), add(multiply(add(const_10, const_1), 4), multiply(4, const_2))), multiply(add(const_10, const_1), 4)), 10))
