5042, 5043, 5044, 5045, 5046, 5047, 5048, 5049, 5050, 5051, ...

Video Solution

Question 162

If $$T_n = \frac{2(n + 2)}{n(n + 1)}$$, for n = 1, 2, 3, ..... Then $$T_6 =$$

Video Solution

Solution

$$T_6=\frac{2\cdot8}{6\cdot7}=\frac{8}{21}$$

Instructions

Answer the questions using the following information.
Given that
1 USD = 70.99 INR, | AUD = 0.708 USD, | EURO = 1.137 USD, and | NZD = 9.679 USD, (Here USD (U) = US Dollar, AUD (A) = Australian Dollar, EURO (FE) = European Union Currency, NZD (N) = Newzealand Dollar, INR (1) = Indian rupee)

Question 163

Increasing order of exchange values of INR (I), NZD (N), EURO (E), AUD (A) with USD is

Video Solution

Solution

We can see that the most expensive currency is NZD while INR is the cheapest.
Also, E is more expensive than AUD.
Hence, option C

Question 164

The currency among the following which has the highest exchange value with EURO is

Video Solution

Solution

1 EUR = 1.137 USD
1 EUR = 1.137*(1/0.708) AUD = 1.605 AUD
1 EUR = 1.137*(1/9.679) NZD = 0.117 NZD

Hence, it can be seen that NZD has the highest value against EUR.

Question 165

The currency which hasthe least exchange value with USD is

Video Solution

Solution

1 INR = 0.014 USD
1 AUD = 0.708 USD
1 EURO = 1.137 USD
1 NZD = 9.679 USD,
Hence, it is clear that INR has the least value against USD

Question 166

The currency among the following whichhas the highest exchange value with AUD is

Video Solution

Solution

1 AUD = 0.708 USD

Hence,
1 AUD = 0.708*70.99INR = 50.26 INR
1 AUD = 0.708*(1/1.137)EUR = 0.622 EUR
1 AUD = 0.708*(1.9.679) NZD = 0.073 NZD

From the above, we can see that NZD has the highest value against AUD and INR has the least value.

For the following questions answer them individually

Question 167

In a certain code if the word WRITE is Coded as 136 and the word STUDYis coded 157, then in the same code the word ‘READ? is Coded as

Video Solution

Question 168

In a code language, the word ‘MISTER’ ig coded as SGWWNS andthe word ‘FOREST’ is coded us ‘UUHVTL’, then the code for the word ‘PERSON’, in the same code language is

Video Solution

Question 169

In a code the letters of the English alphabet are coded by numbers as follows.
$$A\leftrightarrow1, Z\leftrightarrow2, B\leftrightarrow3, Y\leftrightarrow4, C\leftrightarrow5, X\leftrightarrow6 .....$$

Then the code for COME TODAY is

Video Solution

Solution

The entire alphabet can be coded as:
(A,Z) = (1,2) (B,Y) = (3,4) (C, X) = (5,6)
(D,W) = (7,8) (E,V) = (9,10) (F,U) = (11,12)
(G,T) = (13,14) (H,S) = (15,16) (I,R) = (17,18)
(J,Q) = (19,20) (K,P) = (21,22) (L,O) = (23,24)
(M,N) = (25,26)

Hence, COME TODAY gets coded as: 5,24,25,9 14,24,7,1,4

Question 170

In a certain code language HYDERABBD is coded as KBGHUDEDG. Then WARANGAL will be coded in that language as

Video Solution

Solution

2 alphabets are skipped and the next one is substituted in the code.
Hence, WARANGAL gets coded as ZDUDQJDO
