In stadia leveling, the difference in elevation V is computed from the stadia intercept and vertical angle. If the value of stadia constant is 100(assumed errorless) and the errors in the stadia intercept and vertical angle are 0.003 and 45 seconds of arc respectively, evaluate the error in V for stadia intercept=1.200 and vertical angle=15 degrees.
