What is n?

10 is n% of 40
What is n?​

Answer 1

Step-by-step explanation:

$\frac{n}{100} \times 15 = 6 \\ \\ \\ n = \frac{6 \times 100}{15} \\ \\ \\ n = \frac{600}{15} \\ \\ n = 40$

$10 = \frac{n}{100} \times 40 \\ \\ \\ n = \frac{10 \times 100}{40} \\ \\ \\ n = \frac{1000}{40} \\ \\ n = 25$

Answer 2

Answer:

1. 15 x n/100 = 6

15n = 600

n = 600/15 = 40 %

2. 40 x n/100 = 10

40n = 1000

n = 1000/40 = 25 %

Step-by-step explanation:

Verification

1. 15 x 40 /100 = 6
