Find `x` if `x/5-x/6=4` . (a)`-120` (b) `-100` (c) `100` (d) `120`

If 1/5-1/6=4/x , then x= -120\ (b) -100 (c) 100 (d) 120

(65)^(2)-(55)^(2)=?10(b)100(c)120(d)1200

In Fig.105, If A O B and C O D are straight lines. Then x+y= (a) 120 (b) 140 (c) 100 (d) 160

In Fig. 91, A O B\ is a straight line and 4x=5ydot The value of x is (a) 100 (b) 105 (c) 110 (d) 115

The number of terms in te expansion of (1+5x+10x^2+10x^3+x^5)^20 is (A) 100 (B) 101 (C) 120 (D) none of these

Let X={a_(1),a_(2),...,a_(6)} and Y={b_(1),b_(2),b_(3)} The number of functions f from x to y such that it is onto and there are exactly three elements x in X such that f(x)=b_(1) is 75 (b) 90( c) 100 (d) 120

125, 123, 120, 115, 108, 100, 84 (a) 123 (b) 115 (c) 100 (d) 84

12% of 120 is 100.

The number of terms ins (x^3+ 1+ 1/x^3)^100 is (A) 300 (B) 200 (C) 100 (D) 201
