    In a 100 m race, A beats B by 10 m and C by 13 m. In a race of 180 m, B will beat C by:

    ক)
    5.4 m
    খ)
    4.5 m
    গ)
    5 m
    ঘ)
    6 m

    Explanation

    A:B = 100:90. A:C = 100:87. B/C=B/A×A/C= 90/100×100/87 = 30/29. When B runs 30 m, C runs 29 m. When B runs 180 m, C runs {(29/30)×180}m = 174 m. So, B beats C by (180-174)m = 6 m.
