Let N shows the total of frequency. The frequencies for interval 1-5 and 11-15 are 0.216216216216216N and 0.162162162162162N respectively.
Now,
6+ 0.216216216216216N +16+0.162162162162162N+14+10 = N
0.621621621621622N = 46
N = 46 / 0.621621621621622 = 73.999999999999954956521739130462
That in N is 74.
Now frequency for interval 1-5 is
0.216216216216216 *74 = 15.999999999999984
That is frequency of the interval 1-5 is 16.
Now frequency for interval 11-15 is
0.162162162162162*74 = 11.999999999999988
That is frequency of the interval 11-15 is 12.
