If ‘A’ means (÷), ‘B’ means (×), ‘C’ means (+), and ‘D’ means (-), then what is the value of the expression:

Which two signs should be interchanged to make the given equation correct?

15 ÷ 6 - 10 x 5 + 11 = 99

Statements:

A < B ≥ C > U = W; R < Q > L ≤ W = Y; Q > P

Conclusions:

I. B < P

II. C > R

  By interchanging which two signs the question will be correct?

15 + 5 ÷ 2 – 9 × 3 = 22

If 236 = 33, 487 = 57, 6391 = 57, then 851 = ?
