૧. "Only a few" અને "Few" શબ્દો (Modern Pattern)

આજકાલની પરીક્ષાઓમાં "Some" ની જગ્યાએ Few, At least, અથવા Most જેવા શબ્દો વાપરે છે.

• નિયમ: Few, At least, Many, Most — આ બધાનો અર્થ "Some" જ થાય છે.

• જો "Only a few" હોય, તો તેનો અર્થ "Some" અને "Some not" બંને થાય છે.

૨. Negative Statement નો સુવર્ણ નિયમ

જો તમારા બધા વિધાનો (Statements) પોઝિટિવ હોય, તો નિષ્કર્ષ (Conclusion) માં ક્યારેય નેગેટિવ (No / Not) જવાબ સાચો ન હોઈ શકે (જો શક્યતા ના પૂછી હોય તો). આનાથી તમે ડાયરેક્ટ ઓપ્શન એલિમિનેટ કરી શકશો.

વેન આકૃતિ (Venn Diagram) ની માસ્ટર ટિપ્સ:

Syllogism ને ૧૦૦% સાચું સોલ્વ કરવા માટે નીચે મુજબની આકૃતિઓનો મહાવરો રાખવો:

1. All A are B: A નું આખું સર્કલ B ની અંદર.

2. Some A are B: બંને સર્કલ એકબીજાને થોડા છેદે.

3. No A is B: બંને સર્કલ વચ્ચે કોઈ સંબંધ નહીં (વચ્ચે ક્રોસ માર્ક કરી દેવો).
