  5. Question: ` 3.1469 + 6.837 + ? = 15`

    A
    `24.9839`

    B
    `5.7634`

    C
    `5.0161`

    D

    ` .5463`

    C
    ` 5.463`

    D
    `None

    Note: Let, `5463 + 546.3 - 54.63 ÷ x` `= 5999.3` Then,`5463 + 546.3 - (54.63)/x` `= 5999.3` or `6009.3 - (54.63)/x` `= 5999.3` or `54.63/x` `= 6009.3 - 5999.3` or ` 54.63/x` `=10` or x `= 54.63/10` `=5.463`.

    C
    `7/9, 6/7, 3/5`

    D
    `6/7, 7/9, 3/5`

    Note: Coverting each one of the fiven fraction in decimal form ,we get : `5/6=0.833, 6/8` `0.75, 7/9` `= 0.777, 11/13` `= 0.846` Clearly, `0.75 < 0.777 < 0.833 < 0.846` or `6/8 < 7/9 < 5/6 < 11/13`
