    Question

    Some equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.

    5×4×3=705 \times 4\times 3 = 70

    6×5×4=1406 \times 5 \times 4 = 140

    7×6×5=?7 \times 6 \times 5 = ?​​​​​​

    A.

    210

    B.

    220

    C.

    230

    D.

    240

    Correct option is D

    Given:
    5×4×3=705 \times 4\times 3 = 70
    6×5×4=1406 \times 5 \times 4 = 140
    7×6×5=?7 \times 6 \times 5 = ?
    Logic:  
    1st Pair;
    5 × 4 × 3 = 60
    60 + 10 = 70
    2nd Pair;
    6 × 5 × 4 = 120
    120 + 20 = 140
    Now follow this pattern in 3rd pair;
    3rd Pair;
    7 × 6 × 5= 210
    210 + 30 = 240
    So, the correct answer is 240.
    Thus, the correct answer is (d).
