    Direction (1-10): What value should come in place of question mark (?) in the following questions?
    1). 321 × 9 ÷ 0.8 = √? × 11.25

    103037
    103039
    103041
    103043
    103045

    1). Answer: c)
    √? = 321 × 9 / (0.8 × 11.25) = 321
    ? = (321)^2
    ? = 103041

    2. 78.54 ÷ 0.03 + 22.8 ÷ 0.8 - 1470 × 1.25 = ?

    1988.8
    1990
    1992.2
    3). Answer: c)
    12.5 × ? / 100 = 44 × 475 /100 + 72 × 55 / 100
    12.5 × ? / 100 = 209 + 39.6 = 248.6
    ? = 24860 / 12.5 = 1988.8
