Answer 1

438+×÷3=230
438+x=690
x=690-438
x=252

Answer 2

Hope u like my process
=====================
Total runs in the 2 test matches = 180+258

= 438
________________________
If average score in three test increases to 230.

Then,

Total score to be scored in 3 tests =230×3

= 690.

Thus runs required to be scored in 3rd test match = total runs after 3 tests - total runs after 2 tests.

= 690 - 438 =252__(answer) __

So the required runs to be scored in 3rd test match = 252.
