Question

$1162 divided into 3 part such that 4 time first part, 5 time second part and 7 time third part are equal. Find the mean of 3 parts.​

Answer 1

Step-by-step explanation:

Let Part 1 be = x

Part 2 = y

Part 3 = z

According to the question,

4x = 5y = 7z

4x = 5y

x = 5y/4

5y = 7z

z = 5y/7

x + y + z = 1162

5y/4 + y + 5y/7 = 1162

( 35y + 28y + 20y)/ 28 = 1162

83y = 32536

y = 392

x = 5 × 392 / 4 = 490

z = 5 × 392 / 7 = 280

Therefore, the 3 parts of 1162 are 392 , 490 and 280.
