Answer:
Robin= 750
Sharon= 720
Step-by-step explanation:
let the total marks obtained be X
from question, Robin = 5X/6
Shaon= 4X/5
then, 5X/6= 4X/5+30
or, 5X/6= 4X+150/5
or 25X=24x+900
or,X= 900
therefore robin=750
Shaon = 720
Answer:

Step-by-step explanation:
Step-by-step explanation:
∫₀² x f(x²) dx
If u = x², then du = 2x dx, and ½ du = x dx.
When x = 0, u = 0. When x = 2, u = 4.
∫₀⁴ ½ f(u) du
½ (16)
