Solution
The correct option is D310cm Given that, Width of picture =735=385 cm Width of frame =7310=7310 cm ∴ The width to be trimmed =(385−7310) LCM of (5, 10) = 10
Now, let us change each of the given fraction into an equivalent fraction having 10 as the denominator. =(76−73)10=310 Thus, the picture should be trimmed by 310 cm.
