Correct Answer: −, +, ÷, +, =

Solution : Given:
65 * 45 * 25 * 5 * 35 * 60

Let's check the given options –
First option: −, +, −, +, =
⇒ 65 − 45 + 25 − 5 + 35 = 60
Solving the L.H.S. of the equation –
= 125 − 45 − 5
= 75 ≠ 60
Second option : +, ×, +, −, =
⇒ 65 + 45 × 25 + 5 − 35 = 60
Solving the L.H.S. of the equation –
= 65 + 1125 + 5 − 35
= 1195 − 35
= 1160 ≠ 60
Third option : +, −, +, −, =
⇒ 65 + 45 − 25 + 5 − 35 = 60
Solving the L.H.S. of the equation –
= 115 − 25 − 35
= 55 ≠ 60
Fourth option: −, +, ÷, +, =
⇒ 65 − 45 + 25 ÷ 5 + 35 = 60
Solving the L.H.S. of the equation –
= 65 − 45 + 5 + 35
= 105 − 45
= 60

So, only the fourth option satisfies the given equation. Hence, the fourth option is correct.
