Mkey [24]

Answer:

A. \frac{1}{4} = \frac{3}{12}

Step-by-step explanation:

\frac{1}{4} of the students wore shorts.

\frac{3}{12} of the students wore jeans.

Converting the fractions of the students who wore shorts and jeans respectively;

\frac{1}{4} = 0.25

\frac{3}{12} = 0.25

This means that the ratio of students who wore shorts is the same as that of students who wore jeans.

i.e \frac{1}{4} = \frac{3}{12}

Find the compound interest compounded annually on rupees 2700 rate 6 ⅔% per annum and time is 2 years​
dalvyx [7]

<u>Answer:</u>

plz mark me as brainliest ...TOOK ME LONG TIME TO TYPE

answer = CI = 3108 RUPEES

<u>Step-by-step explanation:</u>

i am doing the method in which u find the simple interest of first year then second year.

SI FOR 1ST YEAR= P X R X T / 100

SI = 2700 X 20 X 2 / 3 X 100   ( RATE OF INTEREST IS 20 / 3)

SI = 108000/300

SI = 360

SI FOR SECOND YEAR =

P = 2700 + 360= 3060

SI = 3060 X 20 X 2 / 300

SI= 122400 / 300

SI = 408

COMPOUND INTEREST (CI) = PRINCIPLE + SI OF 2ND YEAR

CI = 2700 + 408

CI = 3108 RUPEES

or u can solve be the method

CI = amount - principle

Amount= principle x (change in ratio) raised to time
