4र 24 का बीचमा n ओटा समानान्तरीय मध्यमाहरु छन् । यदि तेसो मध्यमा र अन्तिम मध्यमाको अनुपात 4:5 भए उक्त श्रेणीमा जम्मा
कतिओटा पदहरु छन् पत्ता लगाउनुहोस् । (There are n arithmetic means between 4 and 24. If the ratio of third mean, to
the last mean is 4:5 then find the number of terms in the series.)
(Ans:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
