Question
Rs. R is invested in a scheme offering 200/4% p.a. for 2
years. The total amount received is Rs. 36,300. If Rs. (R + 2,700) is invested in another scheme offering 18% p.a. for 2 years under simple interest, find the total interest earned.Solution
R × (200/400) × 2 = 36300 – R Or, (R/2) + R = 36300 Or, (3R/2) = 36300 Or, R = 36300 × (2/3) So, R = 24,200 Required interest = (R + 2700) × (18/100) × 2 = (24200 + 2700) × (18/100) × 2 = 26,900 × (9/25) = Rs. 9,684 Correct Option: e) Rs. 9,684
If cos θ + sec θ = √5, then the value of cos³ θ+ sec³ θ is:
If 17sin A = 8, where 0
If A and B are complementary angles, then the value of-
sin A cos B + cos A sin B – tan A tan B + sec 2
If (3cos A - sin A) = 2 cos (90° - A), then find the value of cot A.
What is the simplified value of the given expression?
2(sin² 15° + sin² 75°) + 4sin 30° - (2sec 60° + cot 45°)
If sec2 θ = 4, then find the value of sin2 θ + cosec (90 - θ) where 0o < θ < 90o.
