From I. All Instagram are Google (I) → Conversion → Some Google are Instagram (I) + Only a few Instagram are Facebook (I) → No conclusion. Hence conclusion II does not follow. Some Twitter are Google (I) + [All Instagram are Google (I) → Conversion] → Some Google are Instagram (I) → Probable conclusion → All Twitter can be Instagram (A). Hence conclusion II follows. From II. Some Facebook are Instagram (I) + All Instagram are Google (A) → Some Facebook are Google (I). Hence conclusion I does not follow. All Twitter are Facebook (A) + Some Facebook are Instagram (I) → No conclusion. Hence conclusion II does not follow. From III. All Google are Twitter (A) + No Twitter is a Facebook (E) → No Google is a Facebook (E). Hence conclusion I follows. No Twitter is a Facebook (E) → Conversion → No Facebook is a Twitter (E).

Only Twitter are Google → All Google are Twitter and Twitter can have negative relation with anyone. Hence conclusion I follows but conclusion II does not follow.
23 × 20 + ? = 182 + 92 + 82
19 × ? = 361 ÷ 19
15% of 695 – 12.5% of 250 =? – 1200
(〖(0.4)〗^(1/3) × 〖(1/64)〗^(1/4) × 〖16〗^(1/6) × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3) × 4^(-1/2) ×〖1024〗^(-1/4) ) = ?
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
32 of (16/8) of (30/24) of (120/x) = 30
[(4/3) + (5/6)] of 378 = ?
34 × 5 × 2 ÷ 6 + 7 × 5 + 13 = (?)× 6 – 754
The value of 15 × 14 – 30 + (32 + 17) is:
15 × 18 + 25 × 12 + 30 × 24 = ?% of 1720
