Question

In an examination there were 1600 students if 2/3 and all 130 girls passed then how many boys failed the examination​

Answer 1

Step-by-step explanation:

In an examination there were 1600 students.

No. of girls = 130.

All girls passed.

Then, total boys = 1600 - 130 = 1470.

Hence, no. of boys passed = 2/3 × 1470 = 980.

Then, no. of boys failed the examination = Total boys - Boys passed = 1470 - 980 = 490. ( ANS )
