Hint: Use decimal concept.

We know that, 1 rupee = 100 paise. We can reframe these questions as follows:

18 rupees 9 paise from 75 rupees 80 paise

18 rupees 9 paise can be represented as 18.09 rupees and 75 rupees 80 paise can be represented as 75.80 rupees. Now, on subtracting we’ll get,

75.80−18.09−−−−−− 57.71

Which means 57 rupees 71 paise

49 rupees 79 paise from 123 rupees 68 paise

49 rupees 79 paise can be represented as 49.79 rupees and 123 rupees 68 paise can be represented as 123.68 rupees. Now, on subtracting we’ll get,

123.68 −49.79−−−−−− 73.89

Which means 73 rupees 89 paise.

Note: We can also perform the subtraction by making all units the same that are paise and then subtract.

SOMEONE PLEASE HELP I will mark you BRAINLIST

Answer:

27 degrees

Step-by-step explanation:

We are given that Angle AEF is 63. We can also see that EAF is a right angle. Since angles in a triangle add up to 180, we can use this to solve for AFE:

Angle AEF + EAF + AFE = 180

63 + 90 + AFE = 180

153 + AFE = 180

AFE = 27

<em>Or we can solve it another way</em>

Since EAF is a right angle, the other angles are complementary (they add up to 90) so...

Angle AEF + AFE = 90

63 + AFE = 90

AFE = 27
