Q1:jipmat 2025LRDI › Coding & DecodingMediumLR · MCQ
If '-' stands for 'division', '+' for 'multiplication', '/' for 'subtraction' and 'x' for 'addition', then which one of the following equations is correct?
  • A6+20−12÷7−1=386+20-12\div7-1=38
  • B6−20÷12×7+1=576-20\div12\times7+1=57
  • C6+20−12÷7×1=626+20-12\div7\times1=62
  • D6÷20×12+7−1=706\div20\times12+7-1=70
Pick an option to attempt

The Setup: We map the replacement operators as stated in the rules.
(−⇒÷)(- \Rightarrow \div), (+⇒×)(+ \Rightarrow \times), (÷⇒−)(\div \Rightarrow -), and (×⇒+)(\times \Rightarrow +). Apply standard BODMAS rules.

Step 1: Test the options
Let's directly decode Option D:

Original:
6÷20×12+7−1=706\div20\times12+7-1=70
Substituted:
6−20+12×7÷16 - 20 + 12 \times 7 \div 1

Step 2: Solve via BODMAS
First, handle division and multiplication:

12×7÷1=8412 \times 7 \div 1 = 84
Equation becomes:

6−20+846 - 20 + 84

Add and subtract from left to right:
6−20=−146 - 20 = -14
−14+84=70-14 + 84 = 70

The logic holds up perfectly. Option D is the mathematically sound equation.

Final Answer: 6÷20×12+7−1=706\div20\times12+7-1=70

Q2:jipmat 2025LRDI › Coding & DecodingEasyLR · MCQ
If ROAST is coded as PQYUR in a certain code language, then how will SLOPPY be coded in that language?
  • AMRNAQN
  • BNRMNQA
  • CQNMRNA
  • DQANNMR
Pick an option to attempt

Step 1: Dox the pattern in the first word
Let's map the letter shifts from ROAST to PQYUR:

* R
→\rightarrow P (−2-2)
* O
→\rightarrow Q (+2+2)
* A
→\rightarrow Y (−2-2, wrapping around the alphabet backward)
* S
→\rightarrow U (+2+2)
* T
→\rightarrow R (−2-2)
The hidden mechanic is an alternating shift sequence of
−2-2 and +2+2.

Step 2: Apply the mechanic to the target word
Now we run the exact same
−2,+2-2, +2 sequence on the word SLOPPY:
* S (
−2-2) →\rightarrow Q
* L (
+2+2) →\rightarrow N
* O (
−2-2) →\rightarrow M
* P (
+2+2) →\rightarrow R
* P (
−2-2) →\rightarrow N
* Y (
+2+2) →\rightarrow A (wrapping past Z)

The final generated string is QNMRNA.

Final Answer: QNMRNA

Q3:jipmat 2025LRDI › Coding & DecodingEasyLR · MCQ
If DRIVER = 12, PEDESTRIAN = 20 and ACCIDENT = 16, then CAR is equal to:
  • A3
  • B6
  • C8
  • D10
Pick an option to attempt

The Setup: The numbers given are way too small to be based on the alphabetical positional values (A=1, B=2, etc.). The absolute meta strat here is to simply count the number of letters in each word.

Step 1: Dox the hidden mechanic
*
DRIVER has 6 letters.
6×2=126 \times 2 = 12.
*
PEDESTRIAN has 10 letters.
10×2=2010 \times 2 = 20.
*
ACCIDENT has 8 letters.
8×2=168 \times 2 = 16.
The rule is completely locked in: count the letters and multiply by 2.

Step 2: Apply to the target
*
CAR has exactly 3 letters.
*
3×2=63 \times 2 = 6.

Final Answer: 6
