Olympiad Test : Model Test Paper - Class 6 MCQ

Frog

According to the question,

Given information is, In a certain language "DELHI" is written as 451289. 

The pattern used in this question is an alphabet number like A=1, B=2, C=3......

So,D is the 4th letter, E is the 5th, L is 12th  and so on.

Hence, MUMBAI is equivalent to 132113219

Hence, the answer is 132113219. 

Three times we get a sequence like 378, where 7 is preceded by 3 and followed by 8.

The odd one out from the given group is:

3. Oasis

Explanation:

• Harbour: A harbour is a sheltered area of water where ships can dock safely.
• Coast: The coast is the area where land meets the sea.
• Island: An island is a piece of land completely surrounded by water.

Oasis: An oasis is a fertile area in a desert where water is available. Unlike the other options, which are related to geographic features associated with water bodies, an oasis is specifically associated with desert environments and water sources within them. Therefore, it is the odd one out.

only 3148 is even number

• To evaluate 10P2 × 5Y5
• P implies x and Y implies -
• Putting these in original equation, we get
  10 x 2 x 5-5
• Using BODMAS, We get
  100 - 5 = 95
• Hence, Option 'b' is correct.

Given series: 437523721367542742712276572
Conditions:
7's which are preceded by an even number but not followed by any odd number
Even number → 7 → Not odd number
437523721367542742712276572
Here, we get two 7's which are preceded by an even number but not followed by any odd number
Hence, the correct answer is 2.

5(16)3    (5+3)(5-3)  8x2 = 16
7(24)5    (7+5)(7-5)  12x2 = 24
9(?)6      (9+6)(9-6)  15x3 = 45

The given series is: 17, 23, 29, 35, ?

Each number in the series is obtained by adding 6 to the previous number.

So, to find the missing number, we'll add 6 to 35:

35 + 6 = 41

Therefore, the missing number is 41.

Let's break down the given values and identify any possible patterns:

• For "MAT" = 34:

  • M = 13 (position in the alphabet)
  • A = 1 (position in the alphabet)
  • T = 20 (position in the alphabet)
  • Adding these: 13+1+20=34

• For "DO" = 19:

  • D = 4 (position in the alphabet)
  • O = 15 (position in the alphabet)
  • Adding these: 4+15=19

It appears that the value of each word is the sum of the positions of its letters in the alphabet.

Now, let's apply this rule to "MANGO":

• M = 13
• A = 1
• N = 14
• G = 7
• O = 15

Adding these values: 13+1+14+7+15=50

Therefore, the value for "MANGO" is: 50

213 = 2²13²=419;
322 = 3²22²⁼924;
415 =4²15² = 16125
215 = 2²15² =4125

If DRINK = 6 so here in drink there are 5 letters so 5+1= 6
POLLUTION = 10, so here in pollution there are 9 letters so 9+1 =10
then GOVERNMENT is equal to 11 as it contain 10 letters

Brass is a alloy

take lcm of 5 and 7 = 35

14/35 , 20/35 , 21/35 , 30/35
 so clearly 30/35 is largest so 6/7 is largest
