Explanation

Given:

• 12 people → Rs. 850 in 10 days

• 8 people → Rs. 340 in ? days

Let the required number of days be x.

Use the formula for compound proportion:

12×10​.850=8×x/340​

Step 2: Solve the equation

120./850​=8x/340​

Cross-multiply:

$$120 times 340 = 850 times 8x Rightarrow 40800 = 6800x Rightarrow x = frac{40800}{6800} = 6$$6800=6

Explanation

Step-by-step:

$$frac{31 times 3}{100} = frac{93}{100}, quad frac{7}{5} = frac{140}{100}, quad 20 = frac{2000}{100}$$

Add all:

93+140+2000​/100=2233​/100=22.33

Explanation

Given:

40% of employees didn't go to the meeting, and this equals 28 employees:

40% of x = 28

0.4x = 28

x = 28 / 0.4

x = 70
