A milliammeter had graduations marked 0, 100, 200, 500. The space between 100 mark and
200 mark is divided into 20 divisions. If the pointer of the milliammeter is indicating the seventh
graduation after 100 mark, the current flowing through the circuit is :
(A) 107 mA (B) 135 mA
(C) 170 mA (D) 175 mA

(B) Range = 100/2 5; Position = 7 × 5 = 35 2 = after 100
So, total = 100 + 35 = 135

that will be (B) 135 mA mark as 100 + 7 * (200-100)/20 mA
