    If C/5 = R/4 = (F - 32)/9, what will be the value of C and R if F = 140°?

    ক)
    C = 0, R = 0
    খ)
    C = 60, R = 48
    গ)
    C = 80, R = 100
    ঘ)
    C = 140, R = 140

    Explanation

    Here , c/5= f-32/9      or , c/5 = (140-32)/9 or, c/5=12 or , c = 60 Again , r/4= 60/5 or , r = 12 X 4 or ,r = 48
