Step 1: Work Done by A and B Together

• A’s 1-day work = 1/10
• B’s 1-day work = 1/15
• A and B’s 1-day work together:
  1/10​+1/15​=3/30​+2​/30=5/30​=1/6​
• Work done by A and B in 5 days:
  5×1​/6=5/6​

Step 2: Work Left for C

• Total work = 1
• Work remaining after A and B worked for 5 days: $$1 - frac{5}{6} = frac{1}{6}$$
• C completes the remaining 1/6 of the work in 2 days, so C’s 1-day work:
  1/6​÷2=1/12​

Step 3: Wages Calculation

• Total amount = Rs. 1500

• Work done ratio:

  • A's total work = $frac{5}{10} = frac{1}{2}$
  • B's total work = $frac{5}{15} = frac{1}{3}$
  • C's total work = $frac{2}{12} = frac{1}{6}$

• Share of wages:

  • A's share = $frac{1}{2} times 1500 = 750$
    
  • B's share = $frac{1}{3} times 1500 = 500$
    
  • C's share = $frac{1}{6} times 1500 = 250$
    

• Daily wages:

  • B worked 5 days, so B’s daily wage = 500/5 = Rs. 100
  • C worked 2 days, so C’s daily wage = 250/2 = Rs. 125
  • 100+125 = 225

Explanation

The word "drama" originates from Ancient Greek. 

It comes from the Greek word "δρᾶμα" (drâma), meaning "a deed, action, dramatic performance, play, dramatic event," which in turn is derived from "δράω" (dráō), meaning "to act, to take action, to achieve".

It stores and manages surveillance video data digitally over a network.

Explanation

Step 1: Multiply the coefficients

$$-5\times 10=-50$$

Step 2: Multiply the variables

• $x cdot x = x^2$
  

• $y cdot y = y^2$
  

• $z cdot 1 = z$
  

• $a$ appears once

• $b$ appears once

Step 3: Combine all parts

$$-50abx^2y^2z$$

Explanation

$\lambda =\frac{v}{f}$

Let's plug in our given values and see what we get!

$\lambda =\frac{340\frac{m}{s}}{440s^{-1}}$

$\lambda =0.773m$
