x----chickens

y----ducks

50x+30y=550

44x+36y=532

x=11-3/5y

44x+36y=532

x=11-3/5y

44(11-3/5y)+36y=532

x=11-3/5y

484+48/5y=532 /*5

x=11-3/5y

2420+48y=2660

x=11-3/5y

48y=2660-2420

x=11-3/5y

48y=240 //48

x=11-3/5y

y=5

x=11-3/5*5

y=5

x=8----chicken

y=5-----duck

The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3year
Paha777 [63]

Answer:

Step-by-step explanation:

The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3years and 4months at 18% per annum.Find the sum​

The formula for Simple Interest = PRT

From above question, we have to find the Principal

The simple interest on a certain sum for 5years at 8% per annum is Rs200

Hence,

R = 8%

T = 5 years

Rs 200 = P × 8% × 5

P = 200/8% × 5

P = Rs500

The principal = Rs 500

The simple interest on the same sum for 3years and 4months at 18% per annum.

Simple Interest = PRT

R = 18%

T = 3 years and 4 months

Converted to years

T = 3 + (4 months/12 months)

T = 3.33 years

Hence,

Simple Interest = Rs 500 × 18% × 3.33 years

= Rs 299.7
