Question

The total no of questions in a test appeared by Geeta is 36. If the ratio of the number

of questions answered correctly to the number of questions answered incorrectly by

her is 7 ∶ 2 , find the number of questions she answered incorrectl​

Answer 1

Answer:

Number of questions answered incorrectly = 8

Step-by-step explanation:

Let number of questions correctly answered be 7x

Let number of questions correctly answered be 7xand number of questions incorrectly answered be 2x

Let number of questions correctly answered be 7xand number of questions incorrectly answered be 2xSo, 7x+2x = 36

Let number of questions correctly answered be 7xand number of questions incorrectly answered be 2xSo, 7x+2x = 36=> 9x = 36

Let number of questions correctly answered be 7xand number of questions incorrectly answered be 2xSo, 7x+2x = 36=> 9x = 36=> x = 4

Let number of questions correctly answered be 7xand number of questions incorrectly answered be 2xSo, 7x+2x = 36=> 9x = 36=> x = 4So, number of questions answered incorrectly = 2×4 = 8

Answer 2

Let the number of questions answered correctly be 7x and the number of questions answered incorrectly be 2x.

Total number of questions= 36

ATP,

=> 7x + 2x = 36

=> x = 4

Number of questions incorrectly answered by Geeta = 2 × 4 = 8

Hope this helps!
