Question

One-third of Heena's marks in maths exceed half of her marks in Statistics by 30.If she got 240 marks in the two subjects together,how many marks did she get in Statistics?​

Answer 1

Answer:

Step-by-step explanation:

Let her marks in statistics be x and in maths be y

Now, 1/3x=1/2y+30

x=3/2y+90....1)

Now x+y=240

3/2y+90+y=240

5/2y=240-90

5/2y=150

y=150*2/5

y=30*2

y=60

Therefore her marks in statistics are 60
