Question

Rahul Dravid scored 150 runs in the first test and 228 runs in the second. How many runs should he score in the third test so that his average score in the three tests would be 230 runs ?

1. 112 runs 
2. 300 runs
3. 256 runs 
4. 312 runs
5. None of these

Answer 1

Correct Answer - Option 4 : 312 runs

Given 

In the first test, a Rahul Dravid scored  =  150 runs

In the second test the Rahul Dravid scored  = 228 runs

Formula used 

Average = (Sum of values/ Number of values)

Calculation

Let the runs he should score in third test be x.

Then, (150 + 228 + x)/3 = 230

⇒ (378 + x)/3 = 230

⇒ 378 + x = 690 

⇒ x = 690 – 378 = 312

∴ Rahul Dravid should score 312 runs in third test.
