Answer 1

total marks =100+150
250
42% of 250=105
so english mqrks=105-36=69

Answer 2

Answer:

69 marks in English

Step-by-step explanation:

Maximum marks of Maths = 100

Rani obtained marks in math = 36

Maximum marks of English = 150

Let x be the marks obtained by Rani in English

Total obtained marks = 36+x

Maximum marks in both subjects = 100+150=250

So, Her percentage in combined test = $\frac{36+x}{250} \times 100$

She get 42%

So, $\frac{36+x}{250} \times 100 = 42$

$x=69$

Hence she must get 69 marks in English out of 150 so that she get 42%
