What is the value of `(a+b)/(a-b)` , if `a/b=4?` `3/5` (b) `5/3` (c) `4/5` (d) `5/4`

What is the value of (a+b)/(a-b) , if a/b=4? (a) 3/5 (b) 5/3 (c) 4/5 (d) 5/4

If a/b=4/3, then the value of (6a+4b)/(6a-5b) is (a) -1 (b) 3 (c) 4 (d) 5

If a/b=4/3, then the value of (6a+4b)/(6a-5b) is -1 (b) 3 (c) 4 (d) 5

If cosA=4/5 , then the value of tanA is: (a) 3/5 (b) 3/4 (c) 4/3 (d) 5/3

In Fig. 5.47, the value of cosvarphi is (FIGURE) 5/4 (b) 5/3 (c) 3/5 (d) 4/5

If a=(sqrt(5)+1)/(sqrt(5)-1) and b=(sqrt(5)-1)/(sqrt(5)+1), the value of ((a^(2)+ab+b^(2))/(a^(2)-ab+b^(2))) is (3)/(4) (b) (4)/(3)(c)(3)/(5)(d)(5)/(3)

The roots of x^(2) - (a + 1) x + b^(2) = 0 are equal . Then choose the correct value of a, b from the following option : (a) 5,2 , (b) 3,4 , (c ) 5,-3 , (d) 5,4

If a binary operation * is defined on the set Z of integers as a*b=3a-b, then the value of (2*3)*4 is (a) 2 (b) 3 (c) 4 (d) 5
