Answer 1

Answer :

The given ffigure shows trhe null point is found at 60 cm away from the end a, with x and y as shown.When a resistence of 15 ohm is connected in series with y, the null point is found to shift by 10 cm towards the end a of the wire..

Answer 2

Let the total amount be Rs. p.

Let shares of A and B be Rs. x and Rs. y respectively.

C’s share was Rs. 14

we have, x + y + 14 = p —– (1)

From the given data, x = (p/2) – 4 —– (2)

Remaining amount = p – (p/2 – 4) => p/2 + 4.

y = 1/2(p/2 + 4) + 8 => p/4 + 10 —– (3)

From (1), (2) and (3)

p/2 – 4 + p/4 + 10 + 14 = p

3p/4 + 20 = p

p/4 = 20 => p = Rs. 80.
