  1. Given.   15cotA = 8                  CotA = 8/15                  CotA = B/P         using Pythagoras theorem we can find the third side, Therefore H = 17        sinA = P/H = 15/17        SecA = H/B =17/8

    Given.   15cotA = 8

                     CotA = 8/15

                     CotA = B/P

            using Pythagoras theorem we can find the third side,

    Therefore H = 17

           sinA = P/H = 15/17

           SecA = H/B =17/8

  2. total investment = Rs. 10400 dividend % = 6% market value = Rs. 104 face value = Rs. 100 number of shares = investment ⁄  market value = 10400/104 = 100 dividend = dividend %(face value)× number of shares = 6/100×(100)×100 = Rs. 600 similarly in second case total investment = Rs. 11440 dividend % =Read more

    total investment = Rs. 10400

    dividend % = 6%

    market value = Rs. 104

    face value = Rs. 100

    number of shares = investment ⁄  market value = 10400/104 = 100

    dividend = dividend %(face value)× number of shares

    = 6/100×(100)×100

    = Rs. 600

    similarly in second case

    total investment = Rs. 11440

    dividend % = 10.4%

    M. V. = Rs. 143

    F. V. = Rs. 100

    n= 11440/143= 80

    dividend = 10.4/100 × 100 ×80 = Rs. 832

    total dividend = Rs. (600+832)

    = Rs. 1432.
