Option 2: Rs. 204
Option 3: Rs. 190
Option 4: Rs. 196
Correct Answer: Rs. 204
Solution : Given ratio = $\frac{1}{2} : \frac{2}{3} : \frac{3}{4}$ LCM of 2, 3 and 4 = 12 Now, multiplying all ratios by 12, we get, $(\frac{1}{2} × 12) : (\frac{2}{3} × 12) : (\frac{3}{4} × 12)$ $=6 : 8 : 9$ The sum of the
Question : Silver halides are used in photographic plates because they are
Option 1: oxidised in air
Option 2: soluble in hyposolution
Option 3: reduced in light
Option 4: totally colourless

Question : What will be the remainder when 2654081 + 9 is divided by 266?
Option 1: 8
Option 2: 6
Option 3: 1
Option 4: 9
Correct Answer: 8
Solution : We have, 2654081 + 9 or (266 - 1)4081 + 9 is divided by 266. Dividing 265 by 266 leaves a remainder of – 1. Since 4081 is an odd number. So, remainder when 2654081 is divided by 266 = (–1)4081
Question : Anil and Tirath drove between two points, A and B, 192 km apart.
