Question : Simplify the expression $\frac{s^2+t^2+2 s t-u^2}{s^2-t^2-2 t u-u^2}$, provided $(s+t+u) \neq 0$.
Option 1: $\frac{s+t-u}{s-t-u}$
Option 2: $\frac{s+t+u}{s-t+u}$
Option 3: $\frac{s-t-u}{s+t-u}$
Option 4: $\frac{s-t+u}{s+t+u}$
Correct Answer: $\frac{s+t-u}{s-t-u}$
Solution : Given: $\frac{(s^2+t^2+2 s t)-u^2}{s^2-(t^2+2 t u+u^2)}$ We know $\small a^2+b^2 +2ab = (a+b)^2$ and $\small a^2+b^2-2ab = (a-b)^2$ So, $\frac{(s^2+t^2+2 s t)-u^2}{s^2-(t^2+2 t u+u^2)}=\frac{(s+t)^2 - u^2}{s^2 - (t+u)^2}$ $=\frac{(s+t+u)(s+t-u)}{(s+t+u)(s-t-u)}$ [using $\small a^2 - b^2 = (a+b)(a-b)$] $=\frac{s+t-u}{s-t-u}$ Hence, the correct answer is $\frac{s+t-u}{s-t-u}$.
Question : Subsidiary alliance treaty was imposed on Awadh in ______.
Option 1: 1802
Option 2: 1803
Option 3: 1801
Option 4: 1804

Question : Some students went on a field trip. At a speed of 6 km/hr, they travelled by bike for 2 hours; then at a speed of 2 km/hr, they walked for another hour; then they rested for an hour and had lunch for half an hour; then at a speed of 1 m/s, they walked for an hour to visit a garden; and finally at a speed 4 km/hr, they returned home in 3 hours. Their average speed, in km/hr, (rounded off to two places of the decimal) is:
Option 1: 3.48
Option 2: 129.23
Option 3: 0.28
Option 4: 251.62
Correct Answer: 3.48
Solution : Total distance covered by them = $(6\times2) + (2\times1) + (1×\frac{18}{5}) + (4\times3)$ = $12 + 2 + 3.6 + 12 = 29.6$ km Total time = 2 + 1 + 1.5 + 1 + 3 = 8.5 hr Average speed = $\frac{29.6}{8.5}=$3.48235 = 3.48
Question : Depression formed due to deflating action of winds are called
Option 1: Playas
Option 2: Yardang
Option 3: Ventifacts
Option 4: Sand dunes
Correct Answer: Yardang
Solution : The correct option is Yardang.
Yardangs are geological formations generated in dry or desert locations by the deflating effect of wind. They are the consequence of abrasive wind-blown particles selectively eroding soft or easily erodible sedimentary material. When prevailing winds erode weaker areas of the
Question : The sum of the interior angles of a regular polygon A is 1260 degrees and each interior angle of a regular polygon B is $128 \frac{4}{7}$ degrees. The sum of the number of sides of polygons A and B is:
Option 1: 17
Option 2: 16
Option 3: 19
Option 4: 18
Correct Answer: 16
Solution : The sum of the interior angle Polygon A = 1260° If the sides of the polygon A are nA. ⇒ (nA – 2) × 180° = 1260° ⇒ (nA – 2) = $\frac{1260°}{180°}$ = 7 ⇒ nA = (7 +
Question : Directions: Select the related letter cluster from the given alternatives. BDFH : YWUS :: JLNP : ?
Option 1: QOMK
Option 2: ACEF
Option 3: ZXUT
Option 4: UVWX
Correct Answer: QOMK
Solution : Given: BDFH : YWUS :: JLNP : ?
Like, BDFH : YWUS→(BY, DW, FU, HS) are opposite pairs. Similarly, for JLNP : (?)→(JQ, LO, NM, PK) are opposite pairs.
Thus, JLNP is coded as QOMK. Hence, the first option is correct.
Question : Directions: Select the option figure in which the given figure (X) is embedded as its part (rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of the question figure with all the option figures, the given question figure is embedded only in the second option figure.
Hence, the second option is
