Question

si=975 p=5200 t=2years 6months find rate per annum​

Answer 1

Answer:

7.2 p. c. p. a

Step-by-step explanation:

si=p x t x r / 100

975=5200 x 2.6 x r /100

975=52 x 2.6 x r

975=135.2 x r

r = 975/135.2

r = 7.211

rate = 7.2

Answer 2

Finding rate:

Step-by-step explanation:

$\ Given \ value: \\\\\ Si\ = 975\\\\\ P \ = 5200\\\\\ T \ = 2 \ year \ 6 \ moths \ =2 \ year \ + \frac{6}{12} \\ \\\ T \ =2+\frac{1}{2} \ =2+0.5\\\\\ T \ = 2.5 \\\\\ Find: \\\\\ R = ?\\\\\ formula: \\\\\ S.I \ = \frac{(P \times \ R \times T)}{100} \\\\\ Solution: \\\\\ 975\ =\frac{5200 \times \ R \times \ 2.5 }{100}\\\\\ R=\frac{ 975 \times\ 100}{\ 5200 \times \ 2.5}\\\\\ R=\frac{ 975 \times\ 1000}{\ 5200 \times \ 25}\\\\\ R=\frac{ 39 \times 10}{52}\\\\\ R=\frac{ 39 \times 5}{26}$

$\ R=\frac{ 3 \times 5}{2}\\\\\ R=\frac{ 15}{2}\\\\\ R= 7.5$
