The product of their tens digits is 10 and the product of their units digits is 21. Find the numbers. Solution:<br \/>\nLet the required two 2-digit numbers be 10a + b and 10p + q as per the condition, we have<br \/>\na \u00d7 p = 10 and b \u00d7 q = 21<br \/>\na = 2 and p = 5 or a = 5 and p = 2<br \/>\nSimilarly b \u00d7 q = 21<br \/>\nb = 3 and q = 7 or b = 7 and q = 3<br \/>\n10p + q = 57 or 10p + q = 53<br \/>\nand 10a + b = 23 or 10a + b = 27<br \/>\nSince the units digit of product 1431 is 1.<br \/>\nNumbers are 57 and 23 or 53 and 27.<br \/>\nNow 57 \u00d7 23 = 1311 and 53 \u00d7 27 = 1431 which is given.<br \/>\nHence, the required numbers are 53 and 27.<\/p>\n<p><img
