Hey guys this is a question from the arun sharma alligations chapter ...do let me know how to solve this using the alligations formula :-

A bag contains a total of 105 coins of Rs 1,50 p and 25 p denominations .Find the number of coins of Re 1 if there are a total of 50.5 rupees in the bag and it is known that the number of 25 paise coins are 133.33 % more than the number of 1 rupee coins .

a) 56

b)25

c)24

d)none of these

the answer is C

C) ANSWER

the number of coins of Re 1 are 24, that of 50p are 25 and 25p are 56.

i) 24+25+56= 105 ( first condition)

ii) (1x24) + ( 0.5 x25) + (0.25 x 56) = 50.5 ( second condition)

iii) 56/24 = 2.3333 ( third condition)

to solve this, make three simultaneous equations for all the three conditions given and solve them, you shall get the required answer.

( @ the incognito solver: notice that the question says 133.33 % more... that means that the 25p coins are 233.33 % of the number of Re1 coins, be careful with the language always)

test

test 24 is the correct answer

The ans is none.

from the given data we will get two equations 2.33X+Y=105 and

5.33X+y=210

from equation 1 we can determine that 2.33X is odd(any no. multiplied by odd no. results odd no) so y must be even.

but in 2nd equation Y should be even then only we will get the sum as a even no.

so 1 and 2 are contraversial to each other

so ans is d
