question mistake, please check it. (Question: 170755.3 )


Question:

DIRECTIONS: In a certain instruction system the different computation processes are written as follows.


(a) ‘P × Q + R’ means ‘the product of Q and R is added to P.

(b) ‘P < Q > R’ means ‘the sum of P and Q is divided by one-fourth of R’.

(c) ‘P £ Q $ R’ means ‘R is subtracted from the product of P and Q’.

(d) ‘P △ Q  R’ means ‘R is multiplied by the difference of P and Q’.


You have to find out what will come in the place of the question mark (?) in each question following the computation processes.

16 < 8 > 12 = m

m × 12 + 2 = ?

Options:
A) 46 
B) 42 
C) 32
D) 40
E) 38
Solution:

Ans: (c)

(a) ‘P × Q + R’ means ‘the product of Q and R is added to P.

(b) ‘P < Q > R’ means ‘the sum of P and Q is divided by one-fourth of R’.

(c) ‘P £ Q $ R’ means ‘R is subtracted from the product of P and Q’.

(d) ‘P △ Q  R’ means ‘R is multiplied by the difference of P and Q’.


Given, 16 < 8 > 12 = m

⇒ m = \(\cfrac{16+8}{\cfrac{12}{4}}\)= 8

Then 8 × 12 + 2 = 8 + 24 = 32.

Dear Student,
Its correct, you need to find the value of y from the first exression, which will be put out in 2nd expression to get question mark.
