A piggy bank contains 510. If the number of 20 notes is one more than that of 50. Find the number ofnotes of each type.17.​

Answer»

Answer:

notes of Rs50 is 7

and notes of Rs20 is 8

Step-by-step explanation:

let the note of 50 = X

then, note of 20 = x + 1

total rupees contain piggy BANK = 510

50x + 20(x + 1) = 510

50x + 20X + 20 = 510

70x + 20 = 510

70x = 510 - 20

70x = 490

x = 490/70

x = 7

notes of Rs50 = x = 7

notes of Rs20 = x+1 = 7+1 = 8

54:41=36:xWhat is the value of x ?

Answer»

The VALUE of x is 27.33.

Step-by-step explanation:

Given : 54:41=36:x

To find : The value of x ?

Solution :

When the ratio is in the form,

a:b:: c:d then \frac{a}{b}= \frac{c}{d}

So, here a=54, b=41, c=36 and d=x

Substitute,

\frac{54}{41}= \frac{36}{x}

x=\frac{36\times 41}{54}

x=27.33

THEREFORE, the value of x is 27.33.
