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

54.327 x 357.2 x 0.0057 is the same as :

If log 32x=0.8, then x is equal to

{(441)^1/2 X 207 X (343)^1/3} ÷ {(14)² X  (529)^1/2}

On simplification, 3034 – (1002 20.04) is equal to:

E= (2 x 5 x 10)/(1600)^1/2
W = (4 x 5 x 16)/(32 x 50)^1/2
