Question

if 81 students can do a painting on a wall of length 448 m in 56 days. student do the painting on similar type of wall of length 160 m in 27 days​

Answer 1

Step-by-step explanation:

students × length×days= students × length×days

$81 \times 448 \times 56 = students \times 160 \times 27 \\81 \times 448 \times 56 \div 160 \times 27 = students \\ students = 2032128 \div 4320 \\ students = 470.4$

Answer 2

Answer: 470.4

Step-by-step explanation:

Given,

81 students can do a painting on a wall of length 448 m in 56 days.

∴ 1 student can do a painting on a wall of length 1 m in 1 day = $\frac{1}{81 * 448 * 56}$

∴ Students required to do a similar painting on wall of length 160m in 27 days =  $\frac{160 * 27}{81 * 448 * 56}$  

∴ Students required = 470.4
