I have done your 1st question 2nd, 6th and 7th only because it's so lengthy I know all your answer , but post one question at one time only, ok. it is your answers
it is 6th question
4x + = 15
3x 4 = = 7
Multiplying (1) by 4 and (2) by 6
16x + 24/y = 60
18x 24/ y = 42
Adding (3) and (4), We get
16x + 24/y = 60
+ 18x 24/y = 42
___________
34x = 102
X = 3
Substituting x = 3 in (1), We get
4(3) + 6/y =15 =
6/y =15 -12
y =6/3 = 2
Now,
y = ax - 2
2 = a(3) - 2
3a = 4
a = = 1;
it is 7th question
Given : P = Rs. 7,000; A = Rs job. 9,317 and r = 10%.
T
___
:A = P(1+ 100)"
10
___
9, 317 = 7,000(1+100 )"
9,317. (11 )
____. ___
7,000 = (10)"
1,331. (11)
____. ___
7,000. (10)"
( 11 )³. (11)"
___ =. __
( 10). (10)
On comparing,
n = 3 years
it is 2nd question
Solution
• 1= 4000 * 8*1100 = 320. A = 4000 + 320 = Rs. 4320. For 2nd year. P = Rs. 4320. R = 8%
• |= 4320 x 8 x 1 100 = Rs. 345.60. A = 4320 + 345.60 = 4665.60. Compound interest = Rs. 4665.60 - Rs. 4000 = Rs. 665.60.
• Simple interest for 2 years = 4000 x 8 x 2 100 = Rs. 640 Difference of Cl and St = 66560640 = Rs 25.60.
it is 1st question
For 1st year
P = Rs. 16000
R = 10%
T= 1 year
16000x10x1 = Rs. 1600
_________
100
A = 16000 + 1600 17600
For 2nd year,
P = Rs. 17600
R = 14%
T =1 year
17600x14x1 246400
_________. = ______. = Rs
100. 100
2464.
A = 1760 + 24654 =Rs. 20064
For 3rd year,
P = Rs. 20064
R = 15%
T= 1 year
20064x 15x1
__________. = 3009.60
100
Amount after 3 years = 20064 + 3009.60 = Rs. 23073.60
Compound interest = 23073.60
