Question

If '\(+\)' means '\(\div\)', '\(-\)' means '\(+\)', '\(\div\)' means '\(\times\)' and '\(\times\)' means '\(-\)', then what will be the value of\( (78 \times 45) + 3 -45\div68 \times 13\)?

• A. 3548
• B. 2568
• C. 4038
• D. 3058

Answer 1

The Correct Option is D

Given the following substitutions: 

• + means ÷
• − means +
• ÷ means ×
• × means −

Now, let’s substitute these into the given expression:

(78 × 45) + 3 − 45 ÷ 68 × 13

Substitute × with −, + with ÷, and ÷ with ×:

(78 − 45) ÷ 3 + 45 × 68 − 13

Now, perform the calculations step by step:

1. First, simplify (78 − 45):
   78 − 45 = 33
2. Then divide 33 by 3:
   33 ÷ 3 = 11
3. Now, multiply 45 × 68:
   45 × 68 = 3060
4. Finally, calculate 11 + 3060 − 13:
   11 + 3060 = 3071
   3071 − 13 = 3058

Thus, the value of the expression is 3058.

Therefore, the correct answer is (d) 3058.
