Question 70

If 9 # 3 @ 4 = 31 and 8 # 7 @ 2 = 58, then what will be 5 # 6 @ 7?

Solution

9 # 3 @ 4 = 31 and 8 # 7 @ 2 = 58

the no. we are getting is big so,mul and add plus should be there

consider # = multily

@ = plus

9 # 3 @ 4 = 31

$$9\times 3 + 4$$

apply bodmas rule

$$27 + 4$$ = 31

similary

$$8\times 7 + 2$$

apply bodmas rule

$$56 + 2$$ = 58

so

$$5\times 6 + 7$$

apply bodmas rule

$$30 + 7$$ = 37
