If 2.5% of 50 = a. Then the value of 100a is
1.25
12.5
125
0.125
None of these
2.5% of 50 = a
2.5% of 50 = 50×2.5100=1.25=a
100a = 100 * 1.25 = 125
The mean proportional between 9 and 16 is(a) 12.5(b) 12(c) 5(d) none of these
The total number of terms in the expansion of (x+a)100+(x−a)100 after simplification is
If a x b = a+b-(a/b), then the value of 12 x 4 is
If a=log1218, b=log2454 then the value of ab+5(a-b) is
