Answer:
Step-by-step explanation:
let CP of the article = x
at 5% gain, SP of article = x + (5/100)x = 1.05x
at 5% loss, SP of article = x - (5/100)x = 0.95x
given that 1.05x - 0.95x = 16.5
⇒ 0.1x = 16.5
⇒ x = 16.5/0.1
⇒ x = Rs. 165.
The cost price of the article is Rs. 165.
Answer:
y = 17.5
Step-by-step explanation:
Use the direct proportion equation, y = kx
Plug in the x and y values to solve for k
y = kx
35 = k(140)
0.25 = k
Then, plug in the k value and given x value into the equation, and solve for y
y = kx
y = 0.25(70)
y = 17.5
Answer: ∠A = 20°; ∠B = 59°; ∠C = 101°
Step-by-step explanation:
<u>According to the problem:</u>
- ∠A = ∠A
- ∠B = 4 · ∠A - 21°
- ∠C = 5 · ∠A + 1°
<u>All interior angles within a triangle adds up to 180°:</u>
∠A + ∠B + ∠C = 180°
<u>Substitute in the value of ∠A into the other equations:</u>
∠B = 4 · ∠A - 21° = 4(20°) - 21° = 80° - 21° = 59°
∠C = 5 · ∠A + 1° = 5(20°) + 1° = 100° + 1° = 101°
