A sum of Rs. 4,620 is to be paid back in 2 equal annual instalments. How much is each instalment (in Rs.) if the interest is compounded annually at 10% per annum?
A and B take part in 100 m race. A runs at 5 kmph. A gives B a start of 8 m and still beats him by 8 seconds. The speed of B is:
If \((cos^2\theta-1)(1+tan^2\theta)+2tan^2\theta = 1\), \(0^0\leq\theta\leq90^0\) then \(\theta\) is :
