Answer 1

Step-by-step explanation:

Simple interest is given by I=

100

PTR

.If p=Rs.900, T=2 years, and R=5%, find the simple interest.

Answer 2

Answer:

15) 990

Step-by-step explanation:

As we know,

S.I = P x T x R/100

S.I = 900x2x55/100

S.I = 990

16)

i) 4x - 3y

=> 4×1 - 3×2

=> 4-6 = -2

ii) x+y

=> 1+2 = 3

iii) xy+ 3y+ 9

=> 1×2 + 3×2 + 9

=> 2+6+9 = 17

iv) 2x-y

=>2×1 - 2

=> 2-2 = 0
