Statement:
T > G < E > F = B = Z

This can be interpreted as:
T > G
G < E
E > F
F = B
B = Z (therefore, F = Z)
Conclusions:
I. F = Z

From the statement, F = B and B = Z, so by transitivity, F = Z.
Conclusion I is true.
II. E = B

From the statement, E > F and F = B. Since E is greater than F, and F equals B, E ≠ B.
Conclusion II is false.

Only Conclusion I is true.

.Each of W, X, Y, Z, A, B, and C has a wedding on a different day from Monday to Sunday.
C has to attend a wedding immediately after A.
Y has to attend a wedding on one of the days before both B and W.
Only Z has to attend a wedding before A.
X has to attend a wedding on Friday.
B does not have a wedding on Sunday.
Solution:

Using the given information, let’s organize the days as follows:

Since X’s wedding is on Friday, we know that X is scheduled for Friday.
Since Z is the only person who has a wedding before A, Z must have a wedding on Monday, making A's wedding on Tuesday, with C on Wednesday (as C attends immediately after A).
Since Y's wedding must be before B and W, and X is already set for Friday, Y's wedding can only be on Thursday.
B cannot attend a wedding on Sunday, so B’s wedding must be on Saturday, leaving W for Sunday.
Thus, the schedule is as follows:

Monday - Z
Tuesday - A
Wednesday - C
Thursday - Y
Friday - X
Saturday - B
Sunday - W
Answer: Y has to attend a wedding on Thursday.

Excise tax is an indirect tax, whereas income tax, capital gains tax, and corporate tax are examples of direct taxes in India.
The tax structure in India is a three-tier structure: local municipal bodies, state, and central government. Taxation in India is broadly classified into direct and indirect tax.
 Let us look at these two types of taxes and catch the difference between direct and indirect taxes.
Direct tax is levied on people's income or profits. For example, a taxpayer pays the government for different purposes, including income tax, personal property tax, FBT, etc. 
The burden has to be borne by the person on whom the tax is levied and cannot be passed on to someone else. 
Central Board of Direct Taxes (CBDT) governs and administers the Direct Tax.
Conversely, indirect tax is levied by the government on goods and services.
 Therefore, it can be shifted from one tax-paying individual to another. 
E.g; the wholesaler can pass it on to retailers, who then pass it on to customers. 
Therefore, customers bear the brunt of indirect taxes.
The Central Board of Indirect Taxes and Customs (CBIC) governs and administers indirect taxes.

In Newlands’ Octaves, lithium (Li) and sodium (Na) were observed to have similar properties, as they fall in the same group according to the octaves.
He found that every eighth element had properties similar to that of the first. He compared this to the octaves found in music. 
Therefore, he called it the 'Law of Octaves'. According to the Newlands Octaves, the properties of Lithium and Sodium were found to be the same.

Balancing chemical equations is necessary to satisfy the law of conservation of mass, which states that matter is neither created nor destroyed.
The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form.
 For example, in chemical reactions, the mass of the chemical components before the reaction is equal to the mass of the components after the reaction.

A's work rate = 1/11 (sari per day)
B's work rate = 1/20 (sari per day)
C's work rate = 1/55 (sari per day)

Combined work rate of A and B = (1/11) + (1/20) = (20 + 11) / 220 = 31/220 (sari per day)

Combined work rate of A and C = (1/11) + (1/55) = (5 + 1) / 55 = 6/55 (sari per day)

Work done in 2 days = (31/220) + (6/55) = (31/220) + (24/220) = 55/220 = 1/4 (sari)

Since 1/4 of the work is done in 2 days, it will take approximately 4 cycles to complete the work.
So, 4 cycles * 2 days/cycle = 8 days.

Work done in 8 days = 4 cycles * (1/4 sari/cycle) = 1 sari.

The work can be completed in 8 days.
