the number of indian, malay, and chinese pupils in a school is in the ratio of 1 : 3 : 6. if there are 360 more malay pupils than indian pupils, how many chinese pupils are in the school?

1080

Step-by-step explanation:

looking at the ratio of 1 : 3 : 6, we can say that the pupils are divided into 1 + 3 + 6 = 10 "parts".

Indian are 1 part, Malay are 3 parts, and Chinese are 6 parts.

So 3x (3 parts of malay) is 360 more than 1x (1 part of Indian). Thus:

3x - 360 = x

2x = 360

x = 180

We know chinese is 6 parts, or 6x, so Chinese would be 6 (180) = 1080

Hence, there are 1080 chinese pupils

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
