Answer:
1) 14080
2) 1408
3) 17036.80
Step-by-step explanation:
It is given that
Principal= 12800
Rate of interest =10% p.a
(i) We know that Interest for the first year=
(12800×10×1)/100
= 1280
So the sum due at the end of first year= 12800+1280
= 14080
(ii) Principal for second year = 14080
So the interest for the second year
=(14080×10×1)/100
=1408
iii) We know that Sum due at the end of second year
= 14080+1408
=15488
Here
Principal for third year= 15488
Interest for the third year= (15488×10×1)/100
=1548.80
So the total amount due to him at the end of third year= 15488+1548.80
= 17036.80
2/9 = 14/n
n = 14/2 * 9
n = 7 * 9
n = 63
In short, Your Answer would be 63
Hope this helps!
Answer:
ABC = 30
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+14 + x+7 = 90
Combine like terms
3x+21 = 90
Subtract 21 from each side
3x+21-21 = 90-21
3x = 69
Divide by 3
3x/3 = 69/3
x = 23
ABC = x+7 = 23+7 = 30
