Answer 2

Answer:

Heya!!!

Follow me back....

a. (d) 24

b. (c) W

c. (a) 2bc

d. (d) 0.05

e. (b)x–2

f. (d) 26.352

7. L.C.M.(48, 72, 108):

48=2×2×2×2×3

72=2×2×2×3×3

108=2×2×3×3×3

Thus, L.C.M.(48, 72, 108)=(2×2×3)×2×2×2×3×3×3=2592sec.

2592sec=(2592/60)min.=43.2min

OR 00:43:12

Thus, all the three lights will again change simultaneously at:

=>8:20:00+00:43:12

=>8:63:12

OR

=> At, ...09:03:12

I hope it helps you ^_^
