Answer:
Savings % = 40%
Monthly income = Rs 20,600
Amount spend = Rs 12,360
Step-by-step explanation:
Let the percentage savings be 's'
Percentage savings = 60% + s = 100
s = 100 - 60
s = 40%
This is because, percentages sum up to hundred (100)
Let her monthly income be I
40/100 × I = 8240
40I/100 = 8240
40I = 824000
Divide both side by 40
I = Rs 20,600
Therefore her monthly income is Rs 20,600
Amount she spends
20,600 - 8240
= Rs 12,360
Or 60/100 × 20,600
= Rs 12,360
Answer:
C
Step-by-step explanation:
evaluate each
3(20-12)=48
3(8)=48
24=48 FALSE
3(12-12)=3
3(0)=3
0=3 FALSE
2(12-3)=18
2(9)=18
18=18 TRUE
5(12)-3=58
60-3=58
57=58 FALSE
To solve this you need to know Pythagorean theorem.
First, EG is 24, so the halfway points are 12. Knowing Pythagorean triples, you can use 5,12,13 and 12,16,20.
DF = 5+16
DF = 21
If you don't know Pythagorean triples, I have worked it out on the image attached.
