If P = +, Q = –, R = ×, S = ÷, then insert the proper notations between the successive numbers in the equation: $60 \_ 15 \_ 3 \_ 20 \_ 4 = 20$

Select an option to attempt

Explanation

We test each option by substituting the given symbols:

A. SPRQ → ÷, +, ×, − Expression: $60 ÷ 15 + 3 × 20 − 4$ = $4 + 60 − 4 = 60 ≠ 20$ → Incorrect.

B. QRPS → −, ×, +, ÷ Expression: $60 − 15 × 3 + 20 ÷ 4$ = $60 − 45 + 5 = 20$ → Correct.

C. QRSP → −, ×, ÷, + Expression: $60 − 15 × 3 ÷ 20 + 4$ = $60 − 2.25 + 4 = 61.75 ≠ 20$ → Incorrect.

D. SPQR → ÷, +, −, × Expression: $60 ÷ 15 + 3 − 20 × 4$ = $4 + 3 − 80 = −73 ≠ 20$ → Incorrect.

Hence, the correct option is B. QRPS.
