The upper limit of 5−12.5 is?
Fill in the blanks : (i) Lower class limit of 15-18 is ___ . (ii) Upper class limit of 24-30 is ___. (iii) Upper limit of 5-12.5 is ___. (iv) If the upper and the lower limits of a class interval are 16 and 10; the class interval is ___. (v) If the lower and the upper limits of a class interval are 7.5 and 12.5; the class interval is ___.
The mean proportional between 9 and 16 is(a) 12.5(b) 12(c) 5(d) none of these
Solving (12.5×30)+(15×15)−(8×30)+(25×15), we get
If 2.5% of 50 = a. Then the value of 100a is
