if the sum of two numerrs divided by 15,the divident is 2 and the remainder is 10.if difference between these two numbers is divided by 3the divident is 4 and remainder is 2.find the numbers? |
|
Answer» The required numbers are 23 and 17. Step-by-step explanation: Let the numbers be x and y. We know that Dividend = Divisor × Quotient + Remainder As per the statement, "If the sum of two numbers is divided by 15, the quotient is 2 and the remainder is 10 , we get, x+y=15×2+10 =>x+y=40 --- (1) Also, as the difference of the same numbers is divided by then the quotient is 4 and the remainder is 2, we get x−y=3×4+2 =>x−y=14 --- (2) Adding, equations 1 and 2, we get 2x=54 =>x=27 Substituting, x=27 in the equation (1), we get 27+y=40 =>y=13 Thus the numbers are 27,13.
