Answer:
RS 14400
Step-by-step explanation:
Given the following :
Principal sum = RS 40000
Rate = 2 paisa per 2 rupee per month
Interest at the end of 3 years
1 rupee = 100 paisa
2 Paisa per 2 rupee per month :
2/200 per month = 1 / 100 per month,
Hence rate = 0.01 = 1% monthly
Annual rate = 1% × 12 = 12 % = 0.12
Simple interest :
Principal × rate × time
40000 × 0.12 × 3
40000 × 0.36
= RS 14,400

is the answer hope it helps:)
This polynomial has 4 terms
95% = 0.95
280 - (280 * 0.95)
Answer:
1)
.
2) 
hence, answer is 7/12.
3) We have to divide £72 in the ratio 2:3:1
the total of the ratio is=2+3+1=6
so on dividing 72 into 6 parts we have 72/6=12
First '2' parts=2×12=24
second '3' part=3×12=36
last '1' part=1×12=12
so dividing £72 in the ratio 2:3:1 is: £24,£36 and £12
4) 39 people out of 65 have blonde hair.
Number of people who do not have blonde hair=65-39=26
percentage people who do not have blonde hair is given by:

Hence, percentage people who do not have blonde hair is 40%
5) 20% of 90= (20/100)×90
=18
Hence, 20% of 90 is 18.
6) Factorise

7) Expand

8)
.
9)

10)

11) x= -4 y=3
and z=4 x-y^3
z=4×(-4)-3^3
z= -43
12) 
13) 
Hence x= -2
14) 5,10,15,20,....
Hence, nth term is 5n.
15) (63×128)/32.9=245.106.
16) 938×21=19698.
