Question
A sum of Rs.1000 is divided among P, Q and R such that P
gets Rs.150 more than Q. Q gets Rs.110 more than R. How much does R receive?Solution
Let the amount of money received by Q be Rs x According to the problem, we have the following conditions: P + Q + R = 1000 Q = x, P = x + 150 & x - 110 = R So, According to the question, x + 150 + x + x - 110 = 1000 3x = 1000 - 40 x = 960/3 x = 320 Hence, Q gets Rs 320. Therefore, R gets Rs 320 - 110 = Rs 210Â
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.
...- Find the simplified value of the expression:sin 2 45 o  + sin 2 60 o  - (1/3) X tan 2 60 o
If sin(x-y) = 1  and cos(x+y) = 1 /√2  then what is measure of angle x.
