Abag contains three types of coins i. e. one rupee coins, 50 paisa coins and 25 paisa coins totalling 175 coins. if the total value of the coins of each kind be the same, the total amount in the bag is
a) rs 300 b) rs 175 c) rs 126 d) rs 75

one rupee coin be z

50 paisa coins=2z

25 paisa coins=4z

50/25=2 2z*2=4z

z+2x+4x=175

7z=175

7z/7=175/7

z=25

one rupee coin=25 value

50 paisa rupee coins=50 value

25 rupee coin=100 value

50/25=2 50*2=100

25+50+100=175

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
