Question

Maya, Madhura and Mohsina are friends studying in the same class. In a class test in geography, Maya got 16 out of 25, Madhura got 20. Their average score was 19. How much did Mohsina score???​

Answer 1

Answer:

21

Step-by-step explanation:

$\frac{16 + 20 + x}{3} = 19$

$16 + 20 + x = 19 \times 3$

$36 + x = 57$

$x = 57 - 36$

$x = 21$
