\(\frac{3n}{2p^2}\)
\(\frac{2n}{3p^2}\)
\(\frac{2n}{3p}\)
\(\frac{3n^2}{2p^2}\)
Correct answer is A
M = \(\frac{nk}{p^2}\)
k → \(\frac{mp^2}{n}\) = \(\frac{3x1^2}{2}\)
k = \(\frac{3}{2}\)
: m = \(\frac{3xn}{2p^2}\)
Find the 17term of the Arithmetic Progression (A.P):-6,-1,4
-91
-86
74
79
Correct answer is C
common difference d = -1 - [-6] → -1 + 6
d = 5; a = -6
T\(_n\) = a + (n-1)d
: T\(_{17}\) = -6 + (17 - 1) 5
→ -6 + (16)5
→ -6 + 80 = 74
240%

Correct answer is B
cost price = $50
Selling price = 15 * 8 = $120
percentage profit = \(\frac{sp-cp}{cp}\) * 100 → \(\frac{120-50}{50}\) * 100
percentage profit = 70 * 2 → 140%
If 4\(^{3x}\) = 16\(^{x+1}\), find the value of x

Correct answer is A
4\(^{3x}\) = 4\(^{2(x+1)}\)
3x = 2x + 2
3x - 2x = 2
x = 2

Correct answer is B
23 x 54 = 1242
In mod 7;
1242 ÷ 7 = 177 R 3
Hence; 1242 ≡ 3
