What mathematical signs can be inserted respectively to get a correct equation (calculated left toright ignoring BODMAS) ?

65 _ 30 _ 7 _ 15 _ 5 =15

Correct option is A

Let's analyze each option carefully while calculating left to right and ignoring BODMAS:

1. Option A: 65 − 30 ÷ 7 + 15 − 5

   • 65 - 30 = 35
   • 35 ÷ 7 = 5
   • 5 + 15 = 20
   • 20 - 5 = 15 ,which is correct

2. Option B: 65 − 30 × 7 + 15 − 5

   • 65 - 30 = 35
   • 35 × 7 = 245
   • 245 + 15 = 260
   • 260 - 5 = 255 ,wrong

3. Option C: 65 + 30 − 7 × 15 ÷ 5

   • 65 + 30 = 95
   • 95 - 7 = 88
   • 88 × 15 = 1320
   • 1320 ÷ 5 = 264 ,wrong

4. Option D: 65 + 30 ÷ 7 − 15 − 5

   • 65 + 30 = 95
   • 95 ÷ 7 = 13.57 (not an integer) 

Thus, the correct answer is (A) −, ÷, +, −
