Question

3. IF 250 amounts to 285 in 2 years, then find the rate percent per annum​

Answer 1

Answer:

Step-by-step explanation:

P=250

A=285

T=2 year

SI= A-p

=285-250

=35

SI= 35

R= 35*100/250*2

R=7%

Answer 2

Heya mate!!

$si = \frac{prt}{100}$

$35 = \frac{250 \times 2 \times r}{100} \\ 35 = \frac{20 \times r}{4} \\35 = 5 \times r \\ r = \frac{35}{5} \\ r = 7\%$

Hope it helps u dear✌️✌️
