(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (14, 25, 38) (8, 19, 32)
Option 1: (24, 35, 46)
Option 2: (6, 17, 30)

Question : If $\frac{x}{(b–c)(b+c–2a)}=\frac{y}{(c–a)(c+a–2b)}=\frac{z}{(a–b)(a+b–2c)}$, then $(x+y+z)$ is:
Option 1: $a+b+c$
Option 2: $0$
Option 3: $a^2+b^2+c^2$
Option 4: $2$
Correct Answer: $0$
Solution : Given: $\frac{x}{(b–c)(b+c–2a)}=\frac{y}{(c–a)(c+a–2b)}=\frac{z}{(a–b)(a+b–2c)}$ Let $\frac{x}{(b–c)(b+c–2a)}=\frac{y}{(c–a)(c+a–2b)}=\frac{z}{(a–b)(a+b–2c)}=k$. ${x}=k{(b–c)(b+c–2a)}$ (equation 1) ${y}=k{(c–a)(c+a–2b)}$ (equation 2) ${z}=k{(a–b)(a+b–2c)}$ (equation 3) Adding equations 1, 2, and 3 respectively, we get, $x+y+z=k{(b–c)(b+c–2a)}+k{(c–a)(c+a–2b)}+k{(a–b)(a+b–2c)}$ $x+y+z=k[(b–c)(b+c–2a)+(c–a)(c+a–2b)+(a–b)(a+b–2c)]$ $x+y+z= k[b^2+bc–2ab–bc–c^2+2ac+c^2+ac–2bc–ac–a^2+2ab+a^2+ab–2ac–ab–b^2+2bc)$ $x+y+z$ = 0 Hence, the correct answer is 0.
Question : Evaluate $6.9-[8.6-\{6.5-(5.4-\overline{4.3-2})\}]$
Option 1: 1.8
Option 2: 1.9

Correct Answer: 1.7
Solution : Given: $6.9-[8.6-\{6.5-(5.4-\overline{4.3-2})\}]$ = $6.9-[8.6-\{6.5-(5.4-2.3)\}]$ = $6.9-[8.6-\{6.5-3.1\}]$ = $6.9-[8.6-3.4]$ = $6.9-5.2$ = $1.7$ Hence. the correct answer is 1.7
