Question

if 15 bananas cost rupees 125 find how many bananas can be brought in rupees 200​

Answer 1

Answer:

Step-by-step explanation:

We just need to use simple algebra:-

Let bananas be x,

15x = 125      (15 bananas cost 125 rupees)

[divide by 15 in LHS and RHS]

 x=125/15

 x=25/3

Therefore one banana costs 25/3 rupees.......

Now we use proportionality:-

1 : 25/3 :: y : 200      

( 1 banana for 25/3 rupees is proportionate to y bananas for 200 rupees)                                      

y= 200*1/ 25/3

=200*3/25

=8*3

=24

Therefore he buys 24 bananas with 200 rupees

Answer 2

Answer: 24 bananas

Step-by-step explanation:

Let bananas be x,

rupees be y,

Then y is directly proportional to x.

Y=KX(make K the subject)

K =Y1/X1

K =125/15=25/3

Then, X2=? If Y2 = 200.

X2 = Y2/K

X2 = 200× 3/25 =24 bananas
