In Nepali she got 60 means 60/1
So, 70/3+60=83.3

Answer:
67.5
Step-by-step explanation:
Average of terms = sum of terms / number of terms .
Average in english , math and science is 70 .
∴ 70 = sum of marks / 3
⇒ sum of marks = 70 × 3
⇒ sum of marks = 210
Nepali she got 60 .
Total marks = 60 + 210 = 270
Average of 4 subjects = 270/4
⇒ 135/2
⇒ 67.5
The average is 67.5 .
