How many two-digitnumbers are divisible by3?

Solution :

The list of two-digit numbers divisible by 3is : 12, 15, 18, . . . , 99 Is this an AP?

Yes it is. Here,

a = 12, d = 3,

an = 99. As

an = a + (n – 1) d, we have

99 = 12 + (n – 1) × 3 i.e., 87 = (n – 1) × 3i.e., n – 1 = 87/3 = 29 i.e., n = 29 + 1 = 30So, there are 30 two-digit numbersdivisible by 3. Answer

= cos(–1710°+5×360°)

= cos (–1710° + 1800°)

= cos 90° = 0.

Accounts Accounting Principle

5. Materiality Principle

6. Prudence Principle

5. Materiality Principle: Disclosure of all material facts iscompulsory but it does not imply that even those figureswhich are irrelevant are to be included in the financialstatements. According to this principle, only those itemsor information should be disclosed that have a materialeffect and are relevant to the users. So, an item havingan insignificant effect or being irrelevant to user neednot be disclosed separately, it may be merged with otheritem.If the knowledge about any information is likely toaffect the user’s decision, it is termed as materialinformation.It should be noted that an item material forone enterprise may not be material for anotherenterprise, e.g., an expense of Rs. 50,000 is immaterialfor an enterprise having a turnover of Rs. 100 crore but itis material for an enterprise having a turnover ofRs.10,00,000.

6. Prudence Principle: According to this principle,prospective profit should not be recorded but allprospective losses should immediately be recorded. Theobjective of this principle is not to overstate the profit ofthe enterprise in any case and this concept ensures thata realistic picture of the company is portrayed. Whendifferent equally acceptable alternative methods areavailable, the method having the least favorableimmediate effect on profit should be adopted, e.g.,

1. Valuation of stock at cost or realizable value,whichever is lower.

2. Provision for doubtful debts and provision fordiscount on debtors is made

Mathematics Find the derivative of

tan(2x + 3).

Let f(x) = tan (2x + 3),

u(x) = 2x + 3 and

v( t) = tan t. Then(v o u) (x) = v(u(x))

= v(2x + 3) = tan (2x + 3) = f(x)Thus f is acomposite of two functions. Put t = u(x) =2x + 3. Then (dv/dt) = sec²(t) and(dt/dx) =2exist.Hence,by chainrule(df/dx)=(dv/dt)×(dt/dx)

(df/dx)= 2sec²(2x+3)
