= 12

Q-(2) Sol-(4)

? = 1580 ÷ 63.2

? = 25

Q-(3) Sol-(3)

? = 15.67

Q-(4) Sol-(3)

(13)4.29  = (13)?

? = 4.29

Q-(5) Sol-(2)

? = 10

Q-(6) Sol-(4)



Q-(7) Sol-(1)

Volume of water collected in the tank in 11 hour

⇒0.3×0.2×20×1000=1200 m cubic

If after t hours, the water is at height of 8m,

1200t=200×150×8

⇒t = 200 Hours

Q-(8) Sol-(1)



Q-(9) Sol-(3)



Q-(10) Sol-(3)

The probability of selecting one bag =1/2

Now, probability of getting a white ball from bag A:

=1/2×3/5=3/10

and probability of getting a white ball from bag B:

=1/2×2/6=1/6

Hence, Probability that white ball is drawn either first or second bag:

=3/10+1/6=7/15
