Umar secured 45 marks out of 75 marks. How many marks did he get out of 100 marks?

عمر نے 75 نمبروں میں سے 45 نمبر حاصل کئے۔ اس نے 100 نمبروں میں سے کتنے نمبر حاصل کئے؟

To find the number of marks Umar would get out of 100, we need to calculate his percentage score and then apply it to 100 marks.

Percentage score = (45/75) x 100% = 60%

If he got 60% of 75 marks, he would get 60% of 100 marks, which is:

60% x 100 = 60

So, the correct answer is: 60
