The product of the L.C.M and H.C.F of two numbers is 24. The difference of two numbers is 2. Find the numbers.

The traffic lights at three different road crossings change after every 48 sec 72 sec and 108 sec respectively. If they all change simultaneously at 8: 20: 00 hours, then they will again change simultaneously at

The difference of two numbers is 20% of the number. If the smaller number is 12, the larger one is :

2 + 22 + 222 + 2.22 = ?

24 – [24 –{2.4 x 2-(.024 - ?)}] = 22.0584
