Step-by-step explanation:

Given:

Time taken by A to complete the work = 30 days

Time taken by B to complete the work = 20 days

Concept used:

Divide the sum of money according to the ratio of efficiency

Total work = LCM

Efficiency = (Total work)/(Total time)

Calculations:

Total work = LCM(30 days, 20 days) = 60

Person Time Total work Efficiency

A 30 days 60 60/30 = 2

B 20 days 60 60/20 = 3

Ratio of A's wages and B's wages = 2 ∶ 3

Let the A and B's wages be 2x and 3x respectively

If B receives Rs. 6,000 more wages than A

So, Difference between B and A's wages = 3x – 2x = 6,000

⇒ x = 6000

Total wages of A = 2x = 2 × 6000 = Rs. 12000

∵ A's 30 days wages = 12000

∴ A's per days wages = 12000/30 = Rs. 400

∴ A's 12 days wages = Rs. 400 × 12 = Rs. 4800

∴ A's 12 days wages is Rs. 4,800

Answer:

Q.1.

1.Given details are,

Principal (p) = Rs 3000

Rate (r) = 5%

Time = 2years

Interest for the first year = (3000×5×1)/100 = 150

Amount at the end of first year = Rs 3000 + 300 = Rs 3150

Principal interest for the second year = (3150×5×1)/100 = 157.5

Amount at the end of second year = Rs 3150 + 157.5 = Rs 3307.5

∴ Compound Interest = Rs 3307.5 – Rs 3000 = Rs 307.5

Given details are,

Principal (p) = Rs 3000

Rate (r) = 5%

Time = 2years

Interest for the first year = (3000×5×1)/100 = 150

Amount at the end of first year = Rs 3000 + 300 = Rs 3150

Principal interest for the second year = (3150×5×1)/100 = 157.5

Amount at the end of second year = Rs 3150 + 157.5 = Rs 3307.5

∴ Compound Interest = Rs 3307.5 – Rs 3000 = Rs 307.5

2.Here, P= Rs. 8000,R=10% per annum and n=3 years

Using the formula, A=P(1+100R​)n

Amount after 3 years =8000×(1+10010​)3

=8000×1011​×1011​×1011​

=10648

Thus, amount after 3 years = Rs. 1648.

And compound interest = Rs. (10648−8000)=2648.

Q,2

1. P = ₹27000 ; R = 10% ; T = 1 year

I = prt/100

= ₹27000×10×1/100

= ₹2700

Amount = ₹(27000 + 2700)

= ₹29700
