Mutually inclusive and exclusive
latest answer
Mutually exclusive (or exclusive) frequency distributions define classes where data values belong to only one interval, as the upper limit of one class is the lower limit of the next (e.g., 0–10, 10–20). Mutually inclusive (or inclusive) distributions include both upper/lower limits, often resulting in gaps between intervals (e.g., 0–9, 10–19), frequently requiring conversion to exclusive for analysis.

Circular permutations
Maths & Stats
answered on 26-Mar-26 22:24
Sir, while solving the question about arranging 7 boys around a circular table such that two particular boys never sit together, you first explained that without any restriction the number of ways is (7-1)! = 6! Then, to find the cases where those two boys always sit together, you said we can consider them as one unit. That makes it 6 places, but you mentioned it as 5 places. I am confused about this step. Could you explain it again?
latest answer
Arranging n boys around a circular table is done in (n-1)! ways. For 7 boys its 6! ways When 2 boys are always together then we take these 2 boys as one unit . Now n becomes 6 ( 2 boys as 1 unit + remaining 5 boys) . So total ways is (n-1)! which is 5!. Trust this clarifies

Doubt on the last question

Why is 8P multiplied by the savings?
latest answer
in Eight P Value of P was derived as 50 hence we multiplied eight with 50 4K income - 7P expense = 50 savings k = 2p so 4 x ( 2P) - 7P = 50 8P - 7P = 50 P = 50 Income is 4k i.e 4 x 2P as K = 2_ so income = 8P = 8 x 50 = 400
