1. Find the compound interest and amount ineach of the following:(i) P=3000, R = 5% p.a., Time = 2 years ​

Answer»

Answer:

RS.307.50

Step-by-step explanation:

Principal (P) = Rs.3000

Rate (R) = 5% p.a.

Time (n) = 2 years

Amount (A) = P (1 + R/100)ⁿ

=> A = 3000 (1 + 5/100)²

=> A = 3000 (21/20)²

=> A = Rs.3307.50

Compound Interest = Rs.(3307.50-3000) = Rs.307.50

A number consists of two digits. The product of the digits is 20. When 9 is added tothe number, the digits interchange their places. Find the number.​

Answer»

Step-by-step explanation:

let the two digit no. be =10x + y

and it's 10 place digit = x and unit place digit = y

xy =20............(1)

(10x+y) + 9 = 10Y+ x............(2)

10x - x -10y + y +9 =0

9x - 9y + 9 =0

taking 9 common

x-y +1=0

using y=x +1 , put in eq 1

x × (x+1)=20

x^2+x - 20=0

{x}^{2}  + 5x - 4x - 20 = 0

x(x+5) - 4(x +5)=0

(x-4) (x+5)=0

x=4 , x can't be equal to-5 as in a number DIGITS can't be negative

y=x+1

y = 4+1 =5

no. =10x +y= 10×5+4=50+4 =54

Kajal has a total of rs 590 as curreney notes in the denomination of rupees 50,20,10. the ratioof the number of rupees 50 notes and rupees 20 notes is 3:5. If she has a total of 25 notes , how many notes of each give domination she has?​

Answer» LET the 50₹ note be 3x
& 20₹ be 5x
Then 10₹ note = 25-(3x+5x)
Total NOTES are 25
So according to question
{ 50 x 3x} + { 20 x 5x } + { 10 x ( 25-8x)}= 590
150x+100x+(250-80x)=590
250x-80x=590-250
170x=340
X= 340/170
X = 2

No. Of Rs.50 notes = 3x = 6
No. of Rs. 20 notes = 5x = 10
No. of Rs. 10 notes = 25-(3x+5x)
=25-16
= 9
