P = $3,471.52, the principal
r = 3.1% = 0.031, annual ratr
n = 12, monthly compounding
t = 21 years
Note that n*t = 252.
The value after 21 years is
A = 3471.52*(1 + 0.031/12)²⁵²
= $6,650.91
The interest earned is
6650.91 - 3471.52 = 3179.39

Answer
Find out the how many notes of each denomination did she give .
To prove
Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.
As given
Kamala gave Rs 1,50,000 to her friend.
She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.
Rs50 currency note gave in the denomination = 4x
Rs100 currency note gave in the denomination = 3x
Rs500 currency note gave in the denomination = 5x
than the equation becomes
4x + 3x + 5x = 150000
12x = 150000

x = 12500
Thus
Rs50 currency note gave in the denomination = 4 × 12500
= 50000
Rs100 currency note gave in the denomination = 3 × 12500
= 37500
Rs500 currency note gave in the denomination = 5 × 12500
= 62500
Pretty sure the answer is 5. <em>x</em><em> </em>= 5
The correct answer to your question is k=5 .
