QUESTION: 30

Five bells begin to toll together and toll respectively at intervals of 6, 5, 7, 10 and 12 seconds. How many times will they toll together in one hour excluding the one hour excluding the one at the start?

Solution:

ANS.B

EXP. L.C.M. of 6, 5, 7, 10 and 12 is 420.
So, the bells will toll together after every 420 seconds i.e. 7 minutes.
Now, 7 x 8 = 56 and 7 x 9 = 63.

Thus, in 1 hour (or 60 minutes), the bells will toll together 8 times, excluding the one at the start.

Solution:

ANS. C

EXP. Let the price of an eraser be Rs. x and that of a pen be Rs. y. Then,

6x + 2y = 15 ⇔      …(i)

   (using (i))

⇔84y – 9 (15 – 2y) = 4y (15 – 2y)

⇔ 84y – 135 + 18y = 60y – 8y2

⇔ 8y2 + 42y – 135 = 0

⇔ 8y2 + 60y – 18y – 135 = 0

⇔ 4y (2y + 15) – 9 (2y + 15) = 0

⇔ (2y + 15) (4y - 9) = 0

⇔   y= 9/4                   

⇔ y = 2.25.

Hence, price of a pen = Rs. 2.25.
