Question
In each of the following questions, a sentence is
divided into four parts (A), (B), (C) and (D), One of these parts may contain an error. Identify the part which contains the error, if there is no error, choose option (E) The growing emphasis on data-driven governance in recent years (A) along to initiatives aimed at enhancing transparency and efficiency, (B) have significantly transformed (C) the manner in which public institutions function. (D) No error (E)Solution
The correct phrase is “along with initiatives”, not along to initiatives. This is a preposition usage error.
∆ PQR is right-angled at Q. If ∠R = 60º, then find the value of cosec P.
If tan² 45°- cos² 60° x sin 45° cos 45° cot 30°, then find the value of 'x'.
The value of (3tan10°-tan³10°)/(1-3tan²10°) is equal to
- If sin (4A − B) = (√2/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
sin2 7 ° + sin2 8 ° + sin2 9 ° + sin2 10 ° + ……… + sin2 83 ° = ?
...If cos1.5B = sin(B + 5°), then find the measure of 'B'.
- If sin(A + B) = 1/2 and cos(A + 2B) = √3/2, where 0° < A, B < 90°, then find the value of tan(2A).

cos (sec-1 x) is equal to –
If A + B = 450 , then the value of 2(1 + tanA) (1 + tanB) is:
